The orientation of vapour deposits

Abstract

Abstract Some probable effects of the structure of the critical nucleus on the orientation of the deposit are discussed. From this an expression relating the epitaxial temperature to the incidence rate can be obtained. A change in orientation from a (111) plane parallel to the substrate to a (100) parsllel to the substrate can also be understood on this basis. Finally an explanation is suggested for the parallel orientation of face-centred cubic metals on NaCl.
