Beschreibung
Semiconductors are a class of materials whose electrical conductivity lies between that of a Conductor and of an insulator. Semiconductor Devices plays pivotal role in electronics. There are a lot of Semiconductor devices viz: P-N Junction diode, transistor, LED, Photo diode, FET, MOSFET, UJT, SCR, LDR, Logic gate, amplifier, flip - flop, tunnel diode, PIN diode, triacs, diacs, rectifier etc. Without Semiconductor we can not imagine electronics. When a third doped element is added to a crystal diode in such a way that two P-N Junctions are formed, the resulting device is known as a transistor. Semiconductor devices are used in IC as well as digital world. BJT transistor is very practical transistor. Transistor acts as an amplifier.
