Thyristors are a class of nonlinear electronic device that exhibit bistable resistance--that is, they can be switched between two different conductance states. Thyristors are widely used as inverters (direct to alternating current converters) and for the smooth control of power in a variety of applications such as motors and refrigerators. Materials and(More)
We have studied the degradation mechanism of AlGaAs/InGaAs pseudomorphic HEMTs (PHEMTs) under large signal operation. The output power of the PHEMT is degraded with increasing drain voltage (Vd), temperature, and humidity. The deteriorated devices show a decrease of the maximum drain current (Imax) around the knee voltage (Vk) and an increase of the drain(More)
