Effect of high pressure on transport and structural properties of topological insulator Bi$_2$Se$_3$

ORAL

Abstract

We report a series of electrical resistivity, magnetotransport, and xray diffraction measurements on the topological insulator Bi$_2$Se$_3$ under pressures as high as 34 GPa. The results demonstrate that applied pressure can be used to controllably tune the transport properties without chemical substitution.
