GaAs current-injection negative differential resistance transistors using n+-i-p+-i-n+ structure prepared by molecular beam epitaxy are presented. For p+ with a sheet concentration of 1013 cm-2, a negative differential resistance region is revealed for a base current IB<100 μA. The peak to valley current ratios are about 8 at room temperature. This is proposed to be due to the bipolar-unipolar transition reaction. When IB>=100 μA, the proposed device operates as a conventional bipolar transistor.
