  • Multiterminal lateral S-shaped negative differential conductance device
    Patent number: 5347141
    Abstract: The present invention (or multi-terminal lateral hot-electron transistor, ET) is based on a high electron mobility (hot-electron) transistor with a split-gate arrangement similar to those used in quantum wave guide devices. In the present invention, the depletion below the split gate is used to form, and control, potential barriers between the source and drain contacts. The devices, according to the present invention, exhibit pronounced SNDC which is controlled by the gate bias.
