Pressure-induced superconductivity and its relation to the corresponding Hall coefficient (RH) have been investigated for Bi2Te3, 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 a function of pressure over an extensive range. High-pressure RH measurements reveal a close relation to these complex behaviors; in particular, an abrupt change of dRH/dP is observed in crossing from the nonsuperconducting to the superconducting ambient-pressure phase.
