Activation energy for diffusion of point defects at the surfaces of F.C.C. metals

The energies for migration of vacancies and adatoms and the adatom formation energy at surfaces with low indices have been calculated for aluminum, nickel, copper, palladium, silver, platinum, and gold using the inserted atom method. We have found the self-diffusion activation energies for the jumpwise diffusion mechanism with participation of both types of surface point defect. V. D.

Concentration and displacement waves — General analysis

This article is concerned with the method of static concentration waves (SCW), used in describing ordered phases, and with the theoretical derivation of superstructures. The SCW theory is also generalized to the case of polar superstructures. The symmetry connections are analyzed between SCW and static displacement waves (SDW). Phase relations are obtained between SCW and SDW. The possible experimental consequences of the results obtained are analyzed.V. D.
