It is proposed that the termination of each germanium surface atom in a (111) plane with an ethyl group should provide stabilization of the chemical composition of the surface, chemical stabilization being a prerequisite for the stabilization of electrical properties. The germanium surface is first activated with hydrogen chloride and chlorine gases and then ethylated by exposure to ethyl magnesium bromide. Evaluation by various methods indicates that ethyl groups are reproducibly and strongly bound to the surface in a ratio very close to one ethyl group for each surface atom. Details of the electrical and chemical evaluation are included in the following two papers.
