Diffusion Versus Surface Limitations in Vapor-Solvent Growth of Germanium

Abstract

Measurements of transport rates as functions of pressure in the systems germanium—iodine and germanium—bromine have been carried out. The results are discussed in terms of Lever's theory for diffusive transport. It is concluded that while the germanium—iodine system is highly diffusion limited, the germanium—bromine system is noticeably surface controlled.
