Physics of SrTiO${}_3$-based heterostructures and nanostructures: a review

Abstract

This review provides a summary of the rich physics expressed within SrTiO${}_3$-based heterostructures and nanostructures. The intended audience is researchers who are working in the field of oxides, but also those with different backgrounds (e.g., semiconductor nanostructures). After reviewing the relevant properties of SrTiO${}_3$ itself, we will then discuss the basics of SrTiO${}_3$-based heterostructures, how they can be grown, and how devices are typically fabricated. Next, we will cover the physics of these heterostructures, including their phase diagram and coupling between the various degrees of freedom. Finally, we will review the rich landscape of quantum transport phenomena, as well as the devices that elicit them.
