WebWilliam Shockley proposed the idea of the heterojunction bipolar transistor (HBT) in 1951. He suggested that an emitter region with a wider energy band gap than the base can present an additional barrier for the minority carrier injection from the base region (see Fig. 15 ). This should result in an increased current gain. WebSchottky diode, also known as barrier diode is mainly used in low voltage circuits because the forward voltage drop of the Schottky diode(Vf) is less than a rectifier diode. The … WebSchottky barrier is a depletion layer formed at the junction of a metal and n-type semiconductor. In simple words, schottky barrier is the potential energy barrier formed at the metal-semiconductor junction. The electrons have to overcome this potential energy barrier to flow across the diode. arang serbuk gergaji
