Van Hove Singularity Arising from Mexican-Hat-Shaped Inverted Bands in the Topological Insulator Sn-doped Bi $_{1.1}$ Sb $_{0.9}$ Te $_{2}$ S

Wenchao Jiang, Bowen Li, Xiaomeng Wang +9

The optical properties of Sn-doped Bi $_{1.1}$ Sb $_{0.9}$ Te $_{2}$ S, the most bulk-insulating topological insulator thus far, have been examined at different temperatures over a broad…

Pressure Engineering of the Dirac Fermions in Quasi-One-Dimensional Tl $_{2}$ Mo $_{6}$ Se $_{6}$

Ziwan Song, Bin Li, Chunqiang Xu +6

Topological band dispersions other than the standard Dirac or Weyl fermions have garnered the increasing interest in materials science. Among them, the cubic Dirac fermions were re…

Electron-phonon coupling and superconductivity in the doped topological-crystalline insulator (Pb $_{0.5}$ Sn $_{0.5}$ ) $_{1 - x}$ In $_{x}$ Te

A. Sapkota, Y. Li, B. L. Winn +12

We present a neutron scattering study of phonons in single crystals of (Pb $_{0.5}$ Sn $_{0.5}$ ) $_{1 - x}$ In $_{x}$ Te with $x = 0$ (metallic, but nonsuperconducting) and $x = 0.2$ (nonmetallic…

Growth and Thermo-driven Crystalline Phase Transition of Metastable Monolayer 1T'-WSe2 Thin Film

Wang Chen, Xuedong Xie, Junyu Zong +9

Two-dimensional (2D) transition metal dichalcogenides MX2 (M = Mo, W, X = S, Se, Te) attracts enormous research interests in recent years. Its 2H phase possesses an indirect to dir…

Unusual phonon density of states and response to the superconducting transition in the In-doped topological crystalline insulator Pb $_{0.5}$ Sn $_{0.5}$ Te

Kejing Ran, Ruidan Zhong, Tong Chen +13

We present inelastic neutron scattering results of phonons in (Pb $_{0.5}$ Sn $_{0.5}$ ) $_{1 - x}$ In $_{x}$ Te powders, with $x = 0$ and 0.3. The $x = 0$ sample is a topological crystalline insu…

Nonsymmorphic symmetry protected node-line semimetal in the trigonal YH3

Dexi Shao, Tong Chen, Qinyan Gu +5

Using ab initio calculations based on density-functional theory and effective model analysis, we propose that the trigonal YH3(Space Group: P-3c1) at ambient pressure is a node-lin…
