Abstract

The discovery of a two-dimensional electron gas (2DEG) at the interface between insulating oxides has led to a well-deserved level of excitement due to possible applications as “in-plane” all-oxide nanoelectronics. Here we expand the range of possibilities to the realm of “out-of-plane” nanoelectronics by examining such all-oxide heterostructures as barriers in tunnel junctions.
