Microscopic role of a surfactant in epitaxial crystal growth

  • Seung Mi Lee (a1) and Young Hee Lee (a2)

Abstract

We have investigated the kinetic role of a surfactant in the epitaxial crystal growth of Si/Ge using an ab initio molecular dynamics approach. We find that adsorption and diffusion of an adatom on monohydride Si(001) surface is drastically altered from that on a clean surface in several ways. We particularly emphasize the role of H as a surfactant, and this is further compared to typical group V materials.
