Controlled removal of amorphous Se capping layer from a topological insulator

© 2014 AIP Publishing LLC. We report on the controlled removal of an amorphous Se capping layer from Bi2Te3 and Bi2Se3 topological insulators. We show that the Se coalesces into micron-sized islands before desorbing from the surface at a temperature of ∼150°C. In situ Auger Electron Spectroscopy rev...
