Role of coordinated thermal vibration in atomic-scale interference (IMAGE)
Caption
(a) Fringe pattern obtained experimentally by focusing the electron beam between a pair of neighboring silicon atomic columns.
(b) Calculated result for a model assuming that neighboring atoms vibrate independently of one another (higher-order interference fringes vanish). c: Calculated result for a model incorporating coordinated atomic vibration (which reproduces the experiment). The numbers 2 and 3 in the figure indicate the second- and third-order bright fringes, respectively.
