Electronic Band Alignment at Complex Oxide Interfaces Measured by Scanning Photocurrent Microscopy
The band alignment at an Al(2)O(3)/SrTiO(3) 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 SrTiO(3) layer, cr...
