Tunable 2-dimensional/3-dimensional electron gases by submonolayer La doping of SrTiO_{3}

P. V. Ong, Jaichan Lee, Warren E. Pickett

First-principles calculation was used to study the structural and electronic features of the low dimensional oxide structure, SrTiO_{3}/Sr_{1-x}La_{x}TiO_{3} (x=0.25) superlattices…
