The growth of Bi on both the In-terminated (A) face and the As-terminated (B) face of InAs(1 1 1) has been investigated by low-energy electron diffraction, scanning tunnelling microscopy, and photoelectron spectroscopy using synchrotron radiation. Th

Publikováno v: Physical Review Letters. 114

The prospect of optically inducing and controlling a spin-polarized current in spintronic devices has generated wide interest in the out-of-equilibrium electronic and spin structure of topological insulators. In this Letter we show that only measurin

We have performed angle- and spin-resolved photoemission measurements on Fe${}_{3}$O${}_{4}$(0 0 1)/MgO(0 0 1). Despite intrinsic electron-lattice (polaron) interaction a Fe ${t}_{2g}$ band dispersion is observed, as well as a Fermi surface. The stat
