Abstract
The fabrication of 1.0 mu m gate length enhancement mode high electron mobility transistors (E-HEMTs) in the lattice matched LnAlAs/InGaAs/I nP material system is reported. Typical device DC chacteristics includ e a threshold voltage of 275mV, transconductance of 650mS/mm, output c onductance of 7.0mS/mm, and an off-state breakdown voltage of 16V. The devices exhibited excellent RF performance with an f(t) of 35GHz and an f(max) of 80GHz. For the first time, a process for E-HEMTs lattice matched to InP suitable for circuit applications is presented.
