  • Patent number: 6271544
    Abstract: This invention is a novel silicon carbide and silicon (SiC/Si) heterostructure N-shaped negative-differential-resistance semiconductor switch having low power dissipation and large on/off current ratio. The structure of the semiconductor switch includes Al electrode/p-type single crystal silicon carbide layer/graded-composition layer/n-type single crystal silicon substrate/Al electrode (Al/p-SiC/GCL/n-Si/Al), wherein the graded-composition layer is a buffer layer between the p-SiC and n-Si layers.
