TL;DR: In this paper, the influence of spin-orbit coupling in W(110) on the spin structure of electronic states in deposited Au and Cu monolayers was investigated, and it was shown that the contributions of the spin interaction from W and Au act in opposite directions which leads to a decrease of the resulting spinorbit splitting in the Au monolayer on W110.

TL;DR: It is shown that bulk Bi doping of epitaxial Pb1-x Snx Te (111) films induces a giant Rashba splitting at the surface that can be tuned by the doping level.

TL;DR: In this paper, the Fourier electron optics combined with a retardation field of the detector was used to perform 3D mapping of the Fermi surface in the Brillouin zone along the kz direction.

TL;DR: It is discovered that the STM contrast strongly depends on the bias voltage and reverses its sign beyond 1 V, and it is shown that the understanding of this contrast reversal is the clue to resolving the discrepancy between ARPES and STM results.
