From defect luminescence to cationic mixing: Oxide materials in the STM Oxide materials are omnipresent in science and technology. Given their low carrier density and poor screening ability, oxide properties are often inhomogeneous in space and governed by stoi-chiometry modulations, defects and impurities. Spatially resolving techniques are therefor ... more |
