Surface Structure of Oxygen Annealed Donor Doped SrTiO3(100) Single Crystals Studied with Spectroscopic Electron Microscopy
Source abstract
Abstract
Heating 5at.% (on A-site) La-doped SrTiO3(100) single crystals in an ambient atmosphere at 1300°C for 120 h results in the formation of insulating islands on top of the surface with typical dimensions of up to 50 μm. The islands and the surface between them were investigated by spectroscopic Metastable Impact Electron Emission Microscopy (specMIEEM) and Photoelectron Emission Microscopy in order to determine its electronic and geometric structure.
