Spin resolved photoemission on surface doped topological insulator Bi$_2$Se$_3$
ORAL
Abstract
Topological insulators (TL) have attracted much attention because of their exotic properties. Bi$_2$Se$_3$ is a model TL with a relative large bulk gap and a simple surface state structure. By depositing various impurities on the surface, we were able to fill the topological surface state and higher lying Rashba splitting surface states. The spin texture of the surface electronic structure was determined in spin resolved photoemission measurement.
