In3As

Indium arsenide (InAs) is a III-V compound semiconductor ceramic with a direct bandgap, commonly used in optoelectronic and high-frequency electronic devices. Its narrow bandgap and high electron mobility make it particularly valuable for infrared detectors, high-speed transistors, and quantum well structures where performance at low temperatures or high frequencies is critical. InAs is also explored in emerging applications such as quantum dots and topological materials research, where its unique electronic properties enable novel device architectures not achievable with conventional semiconductors.
