Abstract :
Summary form only given. The authors investigated the transport properties of electrons in delta-doped channels formed both in bulk GaAs and in quantum wells by Hall and Schubnikov-de Haas measurements. They also investigated the DC and microwave characteristics of FETs made from Al0.3Ga0.7As/GaAs heterostructures with a quantum-well delta-doped channel. FETs showed a high drain current capability, large breakdown voltage, low output conductance, large intrinsic transconductance, and large gate voltage swing around maximum transconductance.
