Effect of hydrostatic pressure on transport in the topological insulator Bi${}_2$Te${}_2$Se

Yongkang Luo, Stephen Rowley, Jun Xiong +3

The Hall coefficient $R_H$ and resistivity $\rho$ of the topological insulator Bi${}_2$Te${}_2$Se display a number of puzzling features vs. temperature $T$. We propose a model that descri…
