Stability and Surface Reconstruction of Topological Insulator Bi2Se3 on Exposure to Atmosphere

The stability of the surface of vacuum-cleaved topological insulator Bi2Se3 single crystals is investigated with high-resolution synchrotron-based photoelectron spectroscopy. While the surface is stable at room temperature in vacuum, a Bi2 layer always forms at the surface of Bi2Se3 upon even brief...
