Latest Patents
Wei-Chou Wang holds a patent for a "Negative-differential-resistance heterojunction bipolar transistor with topee-shaped current-voltage characteristics." This invention presents an InP/InGaAlAs heterojunction bipolar transistor that exhibits amplification and negative-differential-resistance phenomena. The 3-terminal current-voltage characteristics of this transistor can be controlled by the applied base current. In the large collector current regime, the transistor behaves similarly to conventional bipolar junction transistors. However, in a small collector current regime, both the active region and negative-differential-resistance loci are observed. The negative-differential-resistance phenomenon arises from the insertion of a thin base layer and a δ-doped sheet. Additionally, the incorporation of a setback layer with a thickness of 50 Å at the emitter-base junction helps suppress the diffusion of doping impurities in the base, thereby improving the confinement of holes injected from the base to the emitter.
