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…
Detecting Chiral Orbital Angular Momentum by Circular Dichroism ARPES
Jin-Hong Park, Choong H. Kim, Jun Won Rhim +1
We show, by way of tight-binding and first-principles calculations, that a one-to-one correspondence between electron's crystal momentum k and non-zero orbital angular momentum (OA…
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…
