Abstract

The kinetics of lateral spreading of Cd₁₈Cu₆ intermetallics along a free Cu surface from Cd source was studied under hydrostatic pressures 0.05 and 0.9 GPa in the temperature range 200-280°C by SEM, AFM and optical microscopy methods. Arrhenius equations for Cd diffusion coefficients over Cd₁₈Cu₆ surface in dependence on pressure were obtained and surface diffusion activation volumes determined. Adatom surface diffusion mechanism with "traps" at the elementary steps is discussed.
