Three-dimensional quasi-quantized Hall insulator phase in SrSi2
Kaustuv Manna, Nitesh Kumar, Sumanta Chattopadhyay +15
In insulators, the longitudinal resistivity becomes infinitely large at zero temperature. For classic insulators, the Hall conductivity becomes zero at the same time. However, ther…
Controlling the 2DEG states evolution at a metal/BiSe interface
Han-Jin Noh, Jinwon Jeong, En-Jin Cho +5
We have demonstrated that the evolution of the two-dimensional electron gas (2DEG) system at an interface of metal and the model topological insulator (TI) BiSe can be cont…
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…
Spin-Chiral Bulk Fermi Surfaces of BiTeI Proven by Quantum Oscillations
Joonbum Park, E. Kampert, Kyung-Hwan Jin +10
We present the Fermi-surface map of the spin-chiral bulk states for the non-centrosymmetric semiconductor BiTeI using de Haas-van Alphen and Shubnikov-de Haas oscillations. We iden…
Anisotropic Dirac fermions in a Bi square net of SrMnBi2
Joonbum Park, G. Lee, F. Wolff-Fabris +8
We report the highly anisotropic Dirac fermions in a Bi square net of SrMnBi2, based on a first principle calculation, angle resolved photoemission spectroscopy, and quantum oscill…
