Oxide heterostructures having spatially separated electron-hole bilayers
Abstract
Oxide heterostructures that form spatially separated electron-hole bilayers are provided. Also provided are electronic devices that incorporate the oxide heterostructures. The oxide heterostructure includes a base layer of SrTiO3, a polar layer of LaAlO2, and a non-polar layer of SrTiO3. Within the oxide heterostructures, a two-dimensional hole gas (2DHG) is formed at the interface between the non-polar layer and the polar layer and a two-dimensional electron gas (2DEG) is formed at the interface between the polar layer and the base layer.
