Webvelocity (usat 21 1 x io7 cm/s) rather than the larger peak velocity. This is attributed to the impact of doping. In context with the reported performance of other HFET designs on InP, our findings suggest that the InAlAs/n+-InP HFET is well- suited to power applications demanding small I,, low gd, and Web(indium aluminum arsenide, InAlAs). Therefore, InP-HEMTs are characterized by high electron mobility, high electron saturation velocity, and high electron concentration. To enhance the high-speed and low-noise characteristics of HEMTs, it is necessary to increase the electorn mobility in the channel.

WebIn the case of alloy materials the temperature dependent saturation velocities are calculated first using ( 3.134 ). For an alloy the model suggests a quadratic interpolation between the saturation velocities for electrons of the basic materials (A and B) depending on the material composition .
