Abstract:
본 발명은 Hole-driven MIT 이론에 근거한 MIT 3 단자 소자인 t-switch의 구현과 t-switch의 응용인 ElectroStatic Discharge (ESD) 잡음 신호를 제거하는 기술을 보여준다. t-switch는 Inlet, Outlet, Control의 3단자로 구성되며 MIT(금속-절연체 전이, 불연속 점프)는 Control 단자에 흐르는 전류에 의해 Outlet 층에서 일어난다. t-switch는 Control 단자에 고저항이 연결되어 Inlet-Outlet으로 소자의 파괴없이 고전류 고전압의 ESD신호가 흐르도록 한다.
Abstract:
PURPOSE: A light emitting device based on a metal-insulator transistion is provided to manufacture a light emitting diode including one of a P-type semiconductor film and a N type semiconductor film by forming a light emitting device with a semiconductor which radiates light through a metal-insulator transition. CONSTITUTION: A buffer layer(420) is formed on a substrate(410). A first electrode(440) is formed on the buffer layer. A semiconductor film is formed in the buffer layer and is separated from the first electrode. The semiconductor layer radiates light according to the voltage supplied to the first electrode and the second electrode. The second electrode(450) is formed in the semiconductor layer.
