Gate-tunable band structure of the LaAlO${}_3$-SrTiO${}_3$ interface

A. E. M. Smink, J. C. de Boer, M. P. Stehno +3

The 2-dimensional electron system at the interface between LaAlO${}_3$ and SrTiO${}_3$ has several unique properties that can be tuned by an externally applied gate voltage. In thi…
