Electronic and Vibrational Excitations on the Surface of the Three-Dimensional Topological Insulator BiTeSe (x = 0, 2, 3)
A. Lee, H. -H. Kung, Xueyun Wang +2
We study surface states in the three-dimensional topological insulators BiTeSe (x = 0, 2, 3) by polarization resolved resonant Raman spectroscopy. By tracking the…
Chiral Spin Mode on the Surface of a Topological Insulator
H. -H. Kung, S. Maiti, X. Wang +3
Using polarization-resolved resonant Raman spectroscopy, we explore collective spin excitations of the chiral surface states in a three dimensional topological insulator, BiSe$…
Surface vibrational modes of the topological insulator BiSe observed by Raman spectroscopy
H. -H. Kung, M. Salehi, I. Boulares +10
We present polarization resolved Raman scattering study of surface vibration modes in the topological insulator BiSe single crystal and thick films. Besides the four Raman…
Raman scattering from the CaC6 superconductor in the presence of disorder
A. Mialitsin, J. S. Kim, R. K. Kremer +1
Polarized Raman scattering has been performed on CaC6 superconductor. We identify two of the three Raman active Eg phonon modes at 440 and 1508 cm-1 expected for the R-3m space gro…
