Generalized semiconductor junction
WebThe lumped-model technique was applied to the characterization of the radiation-induced transient response observed in diodes and transistors. A significant result of the diode analysis was the comparison of the lumped-model response to the solution of the differential equations in describing the diode photocurrent. Application of the lumped-model analysis … WebThe Schottky Diode. The Schottky Diode is a type of metal-semiconductor diode having a low forward voltage drop and a very fast switching speed. The Schottky Diode is another type of semiconductor diode which can be used in a variety of wave shaping, switching and rectification applications the same as any other junction diode.
