Spin Configuration and Scattering Rates on the Heavily Electron-doped Surface of Topological Insulator Bi${}_2$Se${}_3$

Z. -H. Pan, E. Vescovo, A. V. Fedorov +6

Heavily electron-doped surfaces of Bi${}_2$Se${}_3$ have been studied by spin and angle resolved photoemission spectroscopy. Upon doping, electrons occupy a series of {\bf k}-split pai…
