Atomfair 2-inch GaN Single Crystal Wafer (N-type) GaN-FS 2 inch≤2cm-2 400±50 μm C-axis(0001)±0.5° TTV ≤15μm BOW≤20μm

Institutional Procurement & Supply Compliance: As a verified US supplier, Atomfair accepts formal institutional Purchase Orders (POs), contract billing schedules, and custom procurement loops for university and national laboratories, and corporate R&D departments globally.

Gallium Nitride (GaN), a binary III/V direct-bandgap semiconductor widely used in LEDs since the 1990s, boasts a wurtzite crystal structure and exceptional hardness. Its 3.4eV wide bandgap enables superior performance in optoelectronic, high-power, and high-frequency devices-for instance, it serves as the substrate for 405nm violet laser diodes without nonlinear optical frequency doubling. With low sensitivity to ionizing radiation, it suits satellite solar arrays and benefits military/space apps. GaN transistors operate at higher temps and voltages than GaAs ones, ideal for microwave power amplifiers, and show promise for THz devices.
