Physics-guided NMF for phase separation and quantification of STEM-EDXS data
In a strong collaboration with the Swiss Data Science Center, we announce our latest publication From STEM-EDXS data to phase separation and quantification using physics-guided NMF in Machine Learning Science and Technology. In this paper, we present a detailed description of the theoretical principles and functioning of our new algorithm EsPM-NMF in the Python-based espm (…)
Electron beam writing of crystal structure at oxide interfaces
In collaboration with researchers from the Department of Quantum Matter Physics at the University of Geneva, we study the gap between strontium titanate membranes and Nb-doped strontium titanate carrier substrates onto which they have been transferred. In thermally annealed samples, raster scanning an intense STEM electron beam causes the residual Sr, Ti and O atoms (…)
