Sažetak
After the epitaxy of LaAlO3 on a TiO2-terminated surface of SrTiO3, a high-mobility electron gas may appear, which has been the object of numerous works over the last four years. Its origin is a subject of debate between the interface polarity and unintended doping. Here we use electron energy loss "spectrum images", recorded in cross-section in a scanning transmission electron microscope, to analyze the Ti3+ ratio, characteristic of extra electrons. We find an interface concentration of Ti3+ that depends on growth conditions.
