Abstract

We report superconductivity at an onset critical temperature below 3.1 K in topological insulator ∼200-nm-thick Bi₂Te₃ thin films grown by pulsed laser deposition. Using energy-dispersive X-ray spectroscopy elemental mapping and Auger electron spectroscopy elemental depth profiling, we clearly identified bismuth (Bi) precipitation and Bi cluster signatures. Superconductivity in the Bi₂Te₃ films was attributed to the proximity effect of Bi clusters precipitated on the surface of the Bi₂Te₃ films.
