Electron Microscopy

Electron microscopy is a fast-evolving field and new exciting findings can be expected with the advent of recent developments such as spherical aberration correction, monochromated guns or new advances in magnetic imaging techniques such as electron magnetic circular dichroism at the nanometer scale, just to name a few. Real space probes capable of looking at matter with atomic resolution and single atom sensitivity are a reality that provides new googles we can use to look into the nanoworld, and beyond.

Some of challenges in materials physics can only be studied using advanced electron microscopy techniques. Imaging and spectroscopy in the aberration corrected scanning transmission microscope can unravel point defects that trigger a dilute magnetic behavior in superconducting films, help to understand the role of oxygen vacancies and strain in cobaltite thin films, identify spin state superlattices or surface magnetism in nanoparticles, and can also achieve the mapping of minimal lattice distortions associated with light O atoms near interfaces that change drastically the macroscopic properties of complex heterostructures. The combination of electron microscopy, spectroscopy and atomic-scale quantum mechanical calculations represents a unique and extremely powerful tool for resolving the complex mysteries of materials.
