Diffusion energy barrier of Au on Bi2Se3: theory and experiment

The stability and diffusion of ultra-thin thermally deposited Au films on Bi2Se3 was studied using scanning tunneling microscopy and density functional theory calculations. The Au/Bi2Se3 interface is of interest as gold is predicted to provide excellent electrical contact while maintaining the spin-...
