Electron-Stimulated Emission of Na Atoms from NaCl Nanocube Corners
  We performed first principles density functional calculations and simulations of magic-size neutral NaCl nanocubes, and computed the the extraction of a Na neutral corner atom after donating an electron. The atomic structure of the resulting Na corner vacancy is presented.
