摘要: We report the fabrication of enhancement mode InGaAsP/InP metal‐semiconductor field‐effect transistors having gate lengths 2 μm. The epitaxial layers for this structure have been grown by chloride vapor phase epitaxy. devices show extrinsic transconductances as high 220 mS/mm, a short‐circuit current gain cutoff frequency fT=5.2 GHz, and maximum available power fmax=9.5 GHz. A novel technology has utilized where lower band‐gap quaternary InGaAsP layer about 350 thickness is on top InP channel layer.
