Abstract

We report the growth and materials characterization of thin (<35 nm) germanium-carbon alloy (Ge1-xCx) layers grown directly on Si by ultra-high-vacuum chemical vapor deposition. We show that the presence of C atoms is limited to a thin interfacial region at the Si substrate, and interpret this result as a mechanism for strain relief. We also show that the Ge1-xCx films exhibit remarkably low threading dislocation densities despite significant relaxation. copyright The Electrochemical Society.
