Observation of warping effects in the band and angular momentum structures of topological insulator Bi2Te3
Wonsig Jung, Yeongkwan Kim, Beomyoung Kim +10
We performed angle resolved photoemission (ARPES) experiments on Bi2Te3 with circularly polarized light. ARPES data show very strong circular dichroism, indicating existence of orb…
Spin and Orbital Angular Momentum Structures of Cu(111) and Au(111) Surface States
Beomyoung Kim, Choong H. Kim, Panjin Kim +9
We performed angle resolved photoemission (ARPES) studies on Cu(111) and Au(111) surface states with circularly polarized light. Existence of local orbital angular momentum (OAM) i…
Emergence of Orbital Angular Momentum by Inversion Symmetry Breaking and Its Detection by ARPES
Choong H. Kim, Jin-Hong Park, Jun Won Rhim +8
Rashba-split surface band is characterized by a one-to-one correspondence between the electron's momentum k and its spin orientation. Here we show that a similar correspondence bet…
Orbital-Angular-Momentum Based Origin of Rashba-Type Surface Band Splitting
Seung Ryong Park, Choong H. Kim, Jaejun Yu +2
We propose that existence of local orbital angular momentum (OAM) on the surfaces of high-Z materials play a crucial role in the formation of Rashba-type surface band splitting. Lo…
Chiral orbital-angular-momentum in the surface states of Bi2Se3
Seung Ryong Park, Jinhee Han, Chul Kim +11
Locking of the spin of a quasi-particle to its momentum in split bands of on the surfaces of metals and topological insulators (TIs) is understood in terms of Rashba effect where a…
