Electronic Band Alignment at Complex Oxide Interfaces Measured by Scanning Photocurrent Microscopy
Abstract The band alignment at an Al2O3/SrTiO3 heterointerface forming a two-dimensional electron gas (2DEG) was investigated using scanning photocurrent microscopy (SPCM) in an electrolyte-gated environment. We used a focused UV laser source for above-the-bandgap illumination on the SrTiO3 layer, c...
