In-situ ARPES Study of STO/BTO Surface Terminations

ORAL

Abstract

SrTiO3 (STO) has a host of interesting properties, particularly when layered with other complex oxide materials. One such property is a high mobility two-dimensional electron gas (2DEG), which can be generated at the surface of STO when exposed to VUV radiation. Here we study how the 2DEG formation is affected by STO layering and termination. Here we present recent in-situ angle-resolved photo emission studies of MBE grown STO and BTO samples.
