Universality of Electron Mobility in LaAlO${}_3$/SrTiO${}_3$ and bulk SrTiO${}_3$

F. Trier, K. V. Reich, D. V. Christensen +5

Metallic LaAlO${}_3$/SrTiO${}_3$ (LAO/STO) interfaces attract enormous attention, but the relationship between the electron mobility and the sheet electron density, $n_s$, is poorly un…
