1. Eutectic alloys of gallium arsenide with copper, silver, and gold were synthesized and studied. The measured linear-expansion coefficients and Young's moduli can be used to calculate the residual thermal stress in alloyed contacts of gallium arsenide with these metals. 2. A lower residual stress should apparently be expected in gallium arsenide contacts with gold, since …
