Abstract
Ultrasonic velocities, νs, in molten (GaxIn1−x)As pseudo-binary alloys covering the whole composition range have been measured in detail in the temperature range from the liquidus temperature to 1280 °C under the saturated vapour pressure. The isotherm of νs shows a smooth increase from InAs to GaAs. Around the liquidus point, the temperature coefficient of the sound velocity is very small for the InAs and InAs-rich alloy. The results indicate that the sp3 resonance bonding reminiscent of the crystalline state gradually disappears with increasing temperature especially in the InAs-rich alloy.
