Induced Superconductivity In Bi2Se3 Nanostructures By Anneal Doping Of Palladium

ORAL

Abstract

Utilizing thermal annealing at temperatures in excess of 100 Celsius we induce superconductivity in Bi2Se3 by palladium doping. Changes in the material structure are analyzed using a combination of AFM, optical microscopy and Raman spectroscopy. The absorption of Pd results in superconductivity in the material with a transition temperature below 1K. The differential conductance as a function of temperature and magnetic field reveals multiple transitions in the material at several applied currents.
