The Silicon-Doped Gallium Arsenide (GaAs) Single Crystal Wafer is a 2-inch-diameter, N-type conductive semiconductor substrate grown using the Vertical Gradient Freeze (VGF) method. It features a (100) crystal orientation, a thickness of 0.35 mm, and a double-side-polished (DSP) surface.

This Si-doped GaAs wafer has a carrier concentration of (1.60–3.94) × 10¹⁸ cm^-3, carrier mobility of 1400–2100 cm²/(V·s), and resistivity of (1.08–1.90) × 10^-3 Ω·cm. With an average surface roughness (Ra) below 0.4 nm and EPI-ready surface preparation and packing, it is suitable for epitaxial growth, semiconductor research, and thin-film deposition applications.
