  • Abstract
    We describe a new technique which allows one to deduce the mobility profiles under the gate of an ion-implanted GaAs MESFET. The technique is based on the measurements of the transconductance and the series resistance at very low drain-to-source voltages. The experimental results show that the mobility drops to about 1000 cm2/V . s at the channel interface from its maximum value of about 2500 cm2/ V . s.
