Hi there, today is day 2/50 of me making a post talking about semiconductor electrophysics and integrated circuits. The Importance of Extrinsic Semiconductors There are Intrinsic and extrinsic types of semiconductors. The major reason why the switch from Intrinsic to Extrinsic is important is that the intrinsic limitation is limited electrical conductivity, which makes it unsuitable for electronic devices. This switch actually happens by doping, which means adding impurities to Intrinsic materials, thereby making them Extrinsic materials, which in turn have enhanced electrical properties. The Advantages : ·      Improved Conductivity: By doping a semiconductor with specific elements, the charge carrier concentration can be improved. Good examples include doping Silicon with Phosphorus which results in an n-type semiconductor, while dopin that same silicon with boron will result in a p-type semiconductor. ·      Versatility: Extrinsic semiconductors can be used for various range of applications, from low-power devices to high-frequency communication systems and this is due to their high adaptability. Compound Semiconductors and their uses 1.      Gallium Arsenide (GaAs): · High-frequency devices such as microwaves, switches, and detectors. ·      Optoelectronic devices such as photodetectors, and laser diodes amongst others. 2.      Indium Phosphide (Inp): ·      High-speed electronics such as transistors, amplifiers, and switches. ·      Optical communication systems like optical amplifiers. 3.      Gallium Nitride (GaN): ·      Power electronics like transistors, amplifiers, and switches. ·      RF and microwave applications like detectors, amplifiers, and switches.
