Orbital angular momentum driven intrinsic spin Hall effect
Wonsig Jung, Dongwook Go, Hyun-Woo Lee +1
We propose a mechanism of intrinsic spin Hall effect (SHE). In this mechanism, local orbital angular momentum (OAM) induces electron position shift and couples with the bias electr…
Microscopic mechanism for asymmetric charge distribution in Rashba-type surface states and the origin of the the energy splitting scale
Beomyoung Kim, Panjin Kim, Wonsig Jung +9
Microscopic mechanism for the Rashba-type band splitting is examined in detail. We show how asymmetric charge distribution is formed when local orbital angular momentum (OAM) and c…
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…
Existence of Orbital Order and its Fluctuation in Ba(FeCo)As Revealed by X-ray Absorption Spectroscopy
Y. K. Kim, W. S. Jung, G. R. Han +13
We performed temperature dependent X-ray linear dichroism (XLD) experiments on an iron pnictide system, Ba(FeCo)As with =0.00 and 0.05, to experimentally ver…
Electronic Structure Studies of Detwinned BaFeAs by Photoemission
Y. K. Kim, Hyungju Oh, Chul Kim +10
We performed angle resolved photoelectron spectroscopy (ARPES) studies on mechanically detwinned BaFe2As2. We observe clear band dispersions and the shapes and characters of the Fe…
Quasi-particle scattering and protected nature of topological states in a parent topological insulator BiSe
S. R. Park, W. S. Jung, Chul Kim +5
We report on angle resolved photoemission spectroscopic studies on a parent topological insulator (TI), BiSe. The line width of the spectral function (inverse of the quasi-…
