Abstract
A logic gate and a cascaded logic family is described that uses the unique ambipolar behavior, e.g., of carbon nanotubes. A complementary VT-drop ambipolar carbon nanotube logic can provide a decrease in device count compared to previous ambipolar carbon nanotube field effect transistor logic structures, enabling power and/or speed improvements.
Claims21
A system, comprising:
- a logic gate, including an ambipolar device;
