Abstract
A comparison has been made for a bismuth telluride crystal of the structure of (0001) surfaces produced by cleaving in high vacuum, with similar surfaces prepared by the ion-bombardment and annealing technique. The low-energy electron-diffraction patterns of the two surfaces were found to be similar and of approximately the same intensities. Only integral order beams were present. It is concluded that both methods produce essentially clean surfaces with the same atomic arrangements, in the case of this crystal.Keywords
