Abstract

Alloys for addition to a melt of pure germanium to produce a melt from which a semiconductive crystal can be grown consist of Sb and Ga in the proportions 20-60 : 1, and Sb and In in the proportions 1 : 2.5-5. An alloy of As and Ga in unspecified proportions is also mentioned. These alloys are added to the germanium melt in the proportions of 1-100 mg. Sb:Ga alloy, and 5-500 mg. Sb:In alloy respectively to 100 grams of germanium.
