All You Need To Know About Semiconductors Those electronic components which make use of or exploit the electronic characteristics of semiconductor materials such as silicon, germanium, gallium arsenide as well as organic semiconductors are termed as semiconductor Devices. Earlier thermionic devices (vacuum pipes) used to do what semiconductors do today. They use electronic conduction while it is in the solid state as contrasting to the gaseous state in thermionic emission. These devices are manufactured as both, single separate devices as well as Integrated Circuits (ICs), that entail from as low as two to billions of devices manufactured and connected on a distinct semiconductor substrate or wafer. There are four different types of semiconductors, which work for different purposes and each has a different tasks. Here we provide you with the afore-mentioned types of Semiconductors: 1. Diodes conduct electricity easily in one direction among all of their most common behavior. These diodes can come in great varieties such as schottky diodes, zender diodes, varactor, lightemitting diode etc. 2. Transistors are semiconductor devices use in amplifying and switching electronic signals and electronic power. 3. Optoelectronic Devices which use both electronic as well as electronic currents. Some common examples of which are: LED traffic lights etc.
