  • Abstract
    GaAs MESFETs with gate lengths from 300 nm down to 40 nm have been fabricated and characterised at microwave frequencies. The MESFETs have excellent DC and high frequency performance. It is shown that the unity gain cut-off frequency fT, is not inversely proportional to the gate-length, as a consequence of carrier transit delays.
