Normal-incidence steering effect in crystal growth: Ag/Ag(100) - art. no. 081401

摘要

During crystal growth by vapor deposition, normal incident atoms are deflected toward three-dimensional surface structures. The effect becomes strong when the atoms are deposited with a low initial kinetic energy. At low T this steering effect induces an instability in the growth process, causing a perfectly flat surface to become rough after a few monolayers are deposited. Quantitative results for the initial stages of growth of Ag/Ag(100) at T similar to0 K are presented. [References: 19]
