Atomfair 2″ Undoped InAs Single Crystal Wafer Undoped InAs50mm±0.25mm N-type 5×1016 cm-3≥2×104 cm²/V·s<5x104cm-2(100) 500±25μm SSP/DSP

We offer 2”, 3”, 4” Indium Arsenide (InAs) single-crystal wafers—gray cubic crystalline semiconductors composed of indium and arsenic, with a melting point of 942℃. As a direct bandgap material (similar to GaAs), InAs features high electron mobility and a narrow bandgap. It’s ideal for 1-3.8μm infrared detectors (e.g., photovoltaic photodiodes, usable at room temperature for high-power apps or cooled for low noise), diode lasers, and terahertz radiation sources (as a strong photo-Amber emitter). It also works with InP or alloys with GaAs to form InGaAs.
