How doping is done in semiconductors

WebThe content of this video is doping of semiconductors and the PN junction. By adding the right impurity atoms into the semiconductor crystal lattice, the conductivity and the Fermi levels can be manipulated by either adding more electrons called n-doping or more holes called p-doping. This manipulation can be used to create a p-n junction diode ... WebPhysics explains the theories, properties and mathematical approach governing semiconductors. Examples of Semiconductors: Gallium arsenide, germanium, and silicon are some of the most commonly used semiconductors. Silicon is used in electronic circuit fabrication and gallium arsenide is used in solar cells, laser diodes, etc.
