ARPES Studies of Two-Dimensional Electron Gases at Transition Metal Oxide Surfaces
S. McKeown Walker, F. Y. Bruno, F. Baumberger
High mobility two-dimensional electron gases (2DEGs) underpin today's silicon based devices and are of fundamental importance for the emerging field of oxide electronics. Such 2DEG…
Electronic structure of buried LaNiO3 layers in (111)-oriented LaNiO3/LaMnO3 superlattices probed by soft x-ray ARPES
F. Y. Bruno, M. Gibert, S. McKeown Walker +10
Taking advantage of the large electron escape depth of soft x-ray angle resolved photoemission spectroscopy we report electronic structure measurements of (111)-oriented [LaNiO3/La…
A weakly correlated Fermi liquid state with a small Fermi surface in lightly doped SrIrO
Alberto de la Torre, Emily Claire Hunter, Alaska Subedi +7
We characterize the electron doping evolution of (SrLa)IrO by means of angle-resolved photoemission. Concomitant with the metal insulator transition around…
Control of a two-dimensional electron gas on SrTiO3(111) by atomic oxygen
S. McKeown Walker, A. de la Torre, F. Y. Bruno +7
We report on the formation of a two-dimensional electron gas (2DEG) at the bare surface of (111) oriented SrTiO3. Angle resolved photoemission experiments reveal highly itinerant c…
Controlling bulk conductivity in topological insulators: Key role of anti-site defects
D. O. Scanlon, P. D. C. King, R. P. Singh +5
The binary Bi-chalchogenides, Bi2Ch3, are widely regarded as model examples of a recently discovered new form of quantum matter, the three-dimensional topological insulator (TI) [1…
