Superconductivity of the topological insulator Bi<sub>2</sub>Se<sub>3</sub>at high pressure
Superconductivity of the topological insulator Bi<sub>2</sub>Se<sub>3</sub>at high pressure
The pressure-induced superconductivity and structural evolution of Bi2Se3 single crystals are studied. The emergence of superconductivity at an onset transition temperature (Tc) of about 4.4 K is observed at around 12 GPa. Tc increases rapidly to a maximum of 8.2 K at 17.2 GPa, decreases to around 6.5 K at …
