Experimental observation of hidden Berry curvature in inversion-symmetric bulk 2H-WSe2
Soohyun Cho, Jin-Hong Park, Jisook Hong +11
We investigate the hidden Berry curvature in bulk 2H-WSe2 by utilizing the surface sensitivity of angle resolved photoemission (ARPES). The symmetry in the electronic structure of…
Experimental determination of the massive Dirac fermion model parameters for MoS, MoSe, WS, and WSe
Beom Seo Kim, Jun-Won Rhim, Beomyoung Kim +2
Monolayer MX (M = Mo, W; X = S, Se) has drawn much attention recently for its possible application possibilities for optoelectronics, spintronics, and valleytronics. Its exotic…
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…
High resolution angle resolved photoemission studies on quasi-particle dynamics in graphite
C. S. Leem, B. J. Kim, Chul Kim +9
We obtained the spectral function of the graphite H point using high resolution angle resolved photoelectron spectroscopy (ARPES). The extracted width of the spectral function (inv…
