Electron and hole contributions to normal-state transport in the superconducting system SnInTe
Cheng Zhang, Xu-Gang He, Hang Chi +5
Indium-doped SnTe has been of interest because the system can exhibit both topological surface states and bulk superconductivity. While the enhancement of the superconducting trans…
"Forbidden" phonon: dynamical signature of bond symmetry breaking in the iron chalcogenides
David M. Fobes, Igor A. Zaliznyak, John M. Tranquada +8
Investigation of the inelastic neutron scattering spectra in FeTeSe near a signature wave vector for the bond-order wave (BOW) formatio…
Surface-state-dominated transport in crystals of the topological crystalline insulator In-doped PbSnTe
Ruidan Zhong, Xugang He, John A. Schneeloch +8
Three-dimensional topological insulators and topological crystalline insulators represent new quantum states of matter, which are predicted to have insulating bulk states and spin-…
Generic Symmetry Breaking Instability of Topological Insulators due to a Novel van Hove Singularity
Xu-Gang He, Xiaoxiang Xi, Wei Ku
We point out that in the deep band-inverted state, topological insulators are generically vulnerable against symmetry breaking instability, due to a divergently large density of st…
Bulk Signatures of Pressure-Induced Band Inversion and Topological Phase Transitions in PbSnSe
Xiaoxiang Xi, Xu-Gang He, Fen Guan +10
The characteristics of topological insulators are manifested in both their surface and bulk properties, but the latter remain to be explored. Here we report bulk signatures of pres…
Tunable Surface Conductivity in Bi2Se3 Revealed in Diffusive Electron Transport
J. Chen, X. Y. He, K. H. Wu +5
We demonstrate that the weak antilocalization effect can serve as a convenient method for detecting decoupled surface transport in topological insulator thin films. In the regime w…
