The integration of functional oxides on silicon requires the use of complex heterostructures whose properties strongly depend on the strain state.
We show that wavelength-dependent Raman scattering is well adapted to determine the strain state of individual layers in BaTiO3/LaNiO3/CeO2/YSZ structure on Silicon.
