Abstract

Comprehensive DC and high frequency measurements of submicron pseudomorphic AlGaAs/InGaAs MODFETs, InGaAs/GaAs MESFETs, and AlGaAs/InGaAs MISFETs at cryogenic temperatures are discussed. Devices with gate lengths from 0.8 μm to 0.3 μm over a temperature range from 300 K to 110 K were measured. Similar variation in the measured extrinsic current gain cutoff frequency, fT, and similar dependences of the effective electron velocity, veff, with reduced lattice temperature for the different field-effect transistors were determined. These results provide direct experimental evidence that the saturated velocity of electrons is the most important parameter for high speed operation, and with proper design these different pseudomorphic InGaAs/GaAs field-effect transistors provide similar potential for high speed operation.
