Photoelectron Spin Control in Spin-Orbit Systems

ORAL

Abstract

Significant experimental and theoretical interest has followed the observation that the spin polarization of photoelectrons from a topological surface state can be controlled by choice of probing photons.~ We expand these findings by investigating other systems with strong spin-orbit coupling. Spin- and angle-resolved photoemission measurements from a uniquely efficient and high resolution spectrometer using various photon polarizations reveal the extent and limits of this spin-dependent photoemission process.~
