Switching of band inversion and topological surface states by charge density wave
N. Mitsuishi, Y. Sugita, M. S. Bahramy +14
Topologically nontrivial materials host protected edge states associated with the bulk band inversion through the bulk-edge correspondence. Manipulating such edge states is highly…
Nanoscale imaging of unusual photo-acoustic waves in thin flake VTe
A. Nakamura, T. Shimojima, Y. Chiashi +5
Controlling acoustic phonons, the carriers of sound and heat, has been attracting great attention toward the manipulation of sonic and thermal properties in nanometric devices. In…
Strongly spin-orbit coupled two-dimensional electron gas emerging near the surface of polar semiconductors
M. Sakano, M. S. Bahramy, A. Katayama +12
We investigate the two-dimensional (2D) highly spin-polarized electron accumulation layers commonly appearing near the surface of n-type polar semiconductors BiTeX (X = I, Br, and…
Three-dimensional bulk band dispersion in polar BiTeI with giant Rashba-type spin splitting
M. Sakano, J. Miyawaki, A. Chainani +12
In layered polar semiconductor BiTeI, giant Rashba-type spin-split band dispersions show up due to the crystal structure asymmetry and the strong spin-orbit interaction. Here we in…
Bulk Electronic structure of NaCoO.1.3HO
A. Chainani, T. Yokoya, Y. Takata +18
High-energy (h = 5.95 keV) synchrotron Photoemission spectroscopy (PES) is used to study bulk electronic structure of NaCoO.1.3HO, the layered superconducto…
