Cryogenic radiation and particle detectors with superconductors

RESEARCH AREAS

Cryogenic radiation and particle detectors with superconductors

Our research focuses on the development of superconducting radiation and particle detectors, operating at very low temperatures, for astrophysics, particle physics and quantum technologies. Each application requires development of suitable materials and designs, including absorbers, and the study of the relevant physical phenomena that determine their performances.  

Cryogenic detectors based on superconductors display unprecedented performances. Combining nearly zero dark counts, very low thresholds, excellent sensitivity and high quantum efficiency, they are essential for new instruments in astrophysics and cosmology, and are considered next frontier, strategic instrumentation, with applications in quantum technologies, security, biomedicine, environment and several industries.

Our research concentrates on the so-called Transition-Edge Sensors (TES); making use of a very sharp superconducting transition, they constitute extremely sensitive microcalorimeters and bolometers operating at temperatures far below 1K. We accumulate years of expertise in the development of Mo/Au based TES for X-ray astrophysics. Recently we have extended our interests towards the development of prototypes for (1) detection of lower energy photons, in the NIR-VIS-UV, for applications in photonics and astronomy; and (2) phonon detection for direct search of low-mass dark matter.

Quantum transport and light-matter interactions

RESEARCH AREAS

Quantum transport and light-matter interactions

The focus is on electronic transport in bulk crystals and low-dimensional systems, and their interaction with light. We study quantum wells formed at the interface between transition metal oxides, with emphasis on spin-orbit physics and superconductivity. We also study the interaction of electromagnetic waves at optical wavelengths with transition metal systems and photonic crystals. 

We investigate electronic transport in oxide quantum wells in transition metal perovskites (involving, e.g., SrTiO3– and KTaO3- interfaces). Our focus is on Rashba spin-orbit fields and unconventional superconductivity for application in spintronics and quantum technologies. In parallel, we investigate light-matter interactions in different systems. In the area of photonic and plasmonic crystals, our interest is in achieving nonreciprocal propagation of confined electromagnetic waves, tunable with external fields, of interest for integrated photonic circuitry. On the other hand, we investigate the possibility of using electromagnetic waves to entangle spin and orbital degrees of freedom in transition metals. The idea behind is to explore theoretical models and find experimental optical signatures of spin-orbital mixing in strongly correlated systems that could serve as platform to achieve entanglement for quantum technologies.

Gervasi Herranz

Research Leader in Functional Oxide Interfaces and Photonics

The celebrated phrase “the interface is the device” is my favorite motto to describe my research activity, which aims at uncovering new physical phenomena at the boundary of materials, for new concepts and applications.

Until 2008, my focus was on the research on functional oxides, exploiting their magnetic and transport properties. Yet, well before my appointment at ICMAB, my previous scientific experience Ied me to the convincement that exploiting also the optical properties of functional interfaces was an endless source of inspiration for new physics. In 2008, my new permanent position as a tenured researcher at ICMAB-CSIC gave me the opportunity to bring these new ideas and concepts into life.

This background has brought to my major achievements in the fields of oxide functional interfaces and photonics. My most notorious highlights in the last four years include: (i) The possibility of manipulating the electronic structure of oxide quantum wells to realize tailored properties for applications, mainly in electronics (Physical Review Letters 109, 226601 (2012), Scientific Reports 2, 758 (2012), Physical Review Letters 113, 156802 (2014), Nature Communications 6, 6028 (2015), ii) the tuning of electronic orbital polarization at oxide surfaces (Nature Communications 3, 1189 (2012)); the tailoring of the magneto-optic activity exploiting photonic-band effects (ACS Nano, 5, 2957(2011), Nanoscale 3, 4811 (2011)) and (iv) exploiting plasmons for enhanced magnetooptics (Langmuir, 28, 9010 (2012), Physical Review Applied 2, 054003 (2014).

I have supervised three Master Theses and three PhD Theses (two more are in progress). My results have been published in 71 articles (during the last six years I have published 12 articles in journals with index of impact higher than 5) and my h-index is h = 20. I have been awarded with 12 invited lectures in international conferences during the last 6 years (among them, APS March Meeting (twice), MRS Spring, SPIE, CIMTEC and Intermag conferences). I have co-authored a book chapter in the field of photonics (2013). My scientific record is available at http://www.researcherid.com/rid/G-2770-2014.

One of my endeavors has been to be in contact with the scientific community and boost the communication and knowledge exchange. With this in spirit, I have been organizer in two MRS Spring symposia (one as lead coordinator) and I am also leading the organization of one symposium in EMRS 2015 in functional oxides. At the same time, I have been invited as lecturer in different Schools worldwide to lecture on oxide physics and photonics.   

Florencio Sánchez

Research interest
My research activities pivote around the development of functional oxides thin films, mainly magnetic and ferroelectric, and their integration into epitaxial complex heterostructures, with particular interest in the integration with silicon. 

 

Lourdes Fàbrega

Cryogenic radiation detectors, working at temperatures well below 1K, are considered the next generation of instrumentation for a wide variety of applications. Among them, superconducting Transition Edge Sensors (TESs) are nowadays at the frontline. TESs are ultrasensitive microcalorimeters or bolometers useful for a very wide radiation range, from gamma-rays to microwaves and particles. Although initially developed mainly for astronomic instruments, either on ground or in space, their performances, the maturity achieved and the progress on cryogenics have open many other niches for them, in applications such as industry, materials science and quantum information. In particular, TESs have already been installed in electron microscopes and in several synchrotron lines.

My research focuses in the development (design, fabrication and characterization) of X-ray detectors based on Mo/Au-based TES, for Space and other applications, such as dark matter search or materials science. I’m also interested in the physics of these devices: indeed, in spite of the extraordinary development of TES and their achieved performances, there is still room for them to further approach the theoretically predicted limits. Specific work to this end involves understanding the nature of the superconducting transition, and electrothermal modeling to determine and reduce the so-called unexplained noise.

Josep Fontcuberta

I’m mostly interested on functional oxides. These strongly correlated electronic systems display fascinating ferroic (i.e. magnetic, ferroelectric), electric and optical properties, that have motivated my research and that of the group I’ve led. I’m a material’s scientist and I have devoted much effort to the preparation and growth of epitaxies of complex oxides and to the study of the relationship between their structure, microstructure and functional properties. Nowadays, my research activity is focused on exploiting oxide thin films for efficient data storage using magnetic and ferroelectric materials, and their potential use in photovoltaics for energy harvesting and as transparent metallic electrodes. I’m persuaded that oxides can play a very important role in advanced high-tech devices and I’m pushing for the development of either new applications or new-concept devices.

 I’m joining MULFOX (as a RyC scientist) to work within the multifunctional oxides group. My work experience and interests are magnetism and spintronics in mesoscopic systems. Currently, I seek new types of information processing inspired on how the brain works; I consider that exploiting complexity of magnetic and electric signals at the nanoscale is an alternative approach to device miniaturization. I believe there is life outside the lab and we, scientists, must connect our work with society.

The development of today’s electronics is reaching fundamental limits and novel concepts and materials are researched to achieve ever faster and more efficient electronic devices. In this regard, oxides are well positioned, as they display a fascinating complexity of electronic phases –not present in conventional semiconductors–that may open new pathways.

The interface between LaAlO3 and SrTiO3 is the oxide quantum well (QW) par excellence, where superconductivity and magnetism emerge. In LaAlO3/SrTiO3 QWs electrons move in two dimensions forming a two-dimensional electron gas (2DEG, Box a). However, not all the electrons reside in the same QW subband (Box b) and, indeed, they behave differently depending on which orbital are they occupying. We demonstrate that the symmetry of the conduction band inside the QWs can be selected, so that the properties of electrons vary largely. In particular, we show that in the superconductive state Cooper pairs do not bind in the same way either when we change the number of electrons in the 2DEG by electric fields (Box a) or when the direction of confinement is changed (Box b). We also show that choosing the confinement plane allows manipulating the spin-dependent transport in these QWs.

Our work opens a groundbreaking route to manipulate selectively electrons in two dimensions. See more @ G. Herranz at al., Engineering two-dimensional superconductivity and Rashba spin–orbit coupling in LaAlO3/SrTiO3 quantum wells by selective orbital occupancy, Nature Communications 2014, doi:10.1038/ncomms7028.

We show that very diluted dispersions of ferromagnetic metal nanoparticles in diamagnetic hosts show a large, linear response under an applied magnetic field, which is of interest for emerging applications in sensing, integrated optical communications, and magneto-optical current transformers and transducers.  We present also a theory that describes accurately these results and that can be further extended to describe the optical properties of e.g., metal inclusions in polymers or glasses.

Quantum wells at the LaAlO3/SrTiO3 interface with tunable electron states

Quantum wells with d-electrons at the LaAlO3(LAO)/SrTiO3(STO) interface exhibit physical properties, such as superconductivity or magnetism, unseen in conventional semiconductors (Si, Ge, GaAs, …). We have demonstrated that the symmetry of the conduction band inside the QWs can be selected at whish. This opens up novel perspectives to manipulate the electronic properties of QWs at the LAO/STO interface.

 SPINTRONICS WITH NON-MAGNETIC MATERIALS. The neighborhood   makes all difference

It has been discovered that  electric resistance of a nonmagnetic metal (Pt in our case) is depending on  magnetization state of neighboring insulating ferromagnetic layer, namely on the atomic planes forming the interface and their crystallographic orientation.
