Role of d orbitals in the Rashba-type spin splitting for noble-metal surfaces
Hyungjun Lee, Hyoung Joon Choi
We investigate the Rashba-type spin splitting in the Shockley surface states on Au(111) and Ag(111) surfaces, based on first-principles calculations. By turning on and off spin-orb…

Low-velocity anisotropic Dirac fermions on the side surface of topological insulators
Chang-Youn Moon, Jinhee Han, Hyungjun Lee +1
We report anisotropic Dirac-cone surface bands on a side-surface geometry of the topological insulator BiSe revealed by first-principles density-functional calculations. We…
