A focus is on quantitative analyses of the impurity segregation ability of GBs in semiconductors by atom probe tomography (with an impurity detection limit less than 0.005 at.% on a GB simultaneously with a spatial resolution less than 0.4 nm) combined with attomic-resolution STEM and ab-initio calculations, but also the study of atomistic structures of semiconductor nanostructures by in-situ optical measurements (CL, PL, SNOM) under TEM.
