Role of pn junction diode
Web28 Jan 2024 · A P-N junction diode is a two-terminal device made of a p-type semiconductor material and an n-type semiconductor material joined together. The p-type material has a surplus of holes (positive charge carriers) and the n-type material has a surplus of electrons (negative charge carriers). WebP-N junction diode can be used as a photodiode as the diode is sensitive to the light when the configuration of the diode is reverse-biased. It can be used as a solar cell. When the diode is forward-biased, it can be used in LED lighting applications. Based on the refractive index of the medium, the light ray changes its direction, or … The role of the moment of inertia is the same as the role of mass in linear motion… A Zener Diode, also known as a breakdown diode, is a heavily doped semiconduct…
