Conduction-band edge and Shubnikov-de Haas effect in low-electron-density SrTiO3

Abstract

The Shubnikov-de Haas effect is used to explore the conduction-band edge of high mobility SrTiO3 films doped with La. The results largely confirm the earlier measurements by Uwe et al. [Jpn. J. Appl. Phys. 24 (Suppl. 24-2), 335 (1985)]. The band edge dispersion differs significantly from the predictions of ab initio electronic structure theory.
