Sažetak
Using a combination of advanced characterization tools (positron annihilation spectroscopy, conductive-tip atomic force microscopy and high-field magnetotransport), we have studied the extension, origin and properties of the high mobility electron gas (HMEG) generated by etching the SrTiO3 surfaces with Ar+ ions. Contrary to previous assumptions, we show that this HMEG is not confined to nanometric thickness, but extends to a few μ m from the surface. We discuss this unanticipated large spatial extension in terms of the striking large diffusion of oxygen vacancy-related defects.
