"CasFET, or cascade field effect transistor, technology. It introduces a new switching method to transistors, one that is like the effects observed in quantum cascade lasers... transistors that are smaller, use less power and switch from on to off at smaller applied voltages... CasFET does not require band-to-band tunneling"
