Abstract
The first steps of electron irradiation induced modification of a KBr(1 0 0 ) surface have been studied by dynamic force microscopy with atomic resolut ion. Rectangular pits of monatomic depth with not more than one kink site p er pit have been found. The atomic structure of KBr(1 0 0) is preserved at the bottom of the pits. Possible deexcitation and desorption mechanisms are discussed based on these results. (C) 2001 Elsevier Science B.V. All right s reserved.
