Pressure-induced superconductivity and its relation to the corresponding Hall coefficient (${R}_{H}$) have been investigated for Bi${}_{2}$Te${}_{3}$, a known topological insulator, through in situ measurements of magnetoresistance and ac susceptibility with diamond anvil cells. A full phase diagram is presented which shows a complex dependence of the superconducting transition temperature as …
