Abstract

A GaAs voltage-controlled negative differential resistance power transistor using n+-i-p+-i-n+ structure prepared by molecular beam epitaxy (MBE) are presented. The peak-to-valley current ratios (PVRs), peak current densities and generated power outputs can be easily modulated by changing the third external base to emitter bias. A highest PVR of 140 with VBE=0.5V at room temperature has been obtained. This is proposed to be due to the bipolar-unipolar transition reaction. For power consideration, it can be compared with resonant tunneling hot electron transistors.
