1. What is the difference between a conductor, an insulator, and a semiconductor? A conductor is a material that allows the free flow of electric current due to the presence of a large number of free charge carriers. An insulator is a material that resists the flow of el...
A semiconductor is a substance that has specific electrical properties that enable it to serve as a foundation for computers and other electronic devices. It is typically a solid chemical element or compound that conducts electricity under certain conditions but not others. This makes it an ideal m...
What is a diode? Electrical, Fundamentals A diode is a semiconductor device that essentially acts as a one-way switch for current. It allows current to flow easily in one direction, but severely restricts current from flowing in the opposite direction. Diodes are also known as rectifiers ...
A single integrated circuit (IC), such as a microprocessor chip, can do the work of a set of vacuum tubes.Semiconductor MaterialsThere are several materials and elements used to make semiconductor. The basic requirement is that the material should not be a very good conductor of electricity, ...
It is least used diode. The process of the backward diode is similar to the tunnel diode. It can be used in some applications where it is needed. Gunn Diode It is a PN Junction diode and it is similar to the semiconductor device which has two terminals. It is also known as ...
A light-emitting diode (LED) is a semiconductor device that emits light when an electric current flows through it. Based on the semiconductor material used and the amount of doping, an LED will emit a coloured light at a particular spectral wavelength wh
1. What is a diode Diodes started as “valves”- the devices that allow unidirectional current flow but slowly evolved into semiconductors for half a century. 24-year-old German physicist Ferdinand Braun proposed the idea of semiconductor diodes. The inventor of the cathode ray tube (CRT) ...
A metal-semiconductor diode having high speed of switching and very low forward biasing voltage drop is known as Schottky diode. The symbol used for Schottky diode is as: Construction of Schottky Diode A Schottky diode is made up by overlapping a metal such as gold, silver, tungsten or alumin...
Schottky Barrier Diodes (SBD) Schottky barrier diodes utilize a Schottky barrier consisting of a metal-semiconductor junction.This results in much lower VF characteristics (forward voltage drop) compared with a PN junction diodes, enabling faster switching speeds. Zener Diode (ZD) Zener diodes are ...
Softness Factor: The softness factor of power diodes is the ratio of charge removal times from the semiconductor and depletion regions, indicating voltage transients upon turn-off. What is a Power Diode? A power diode is defined as a diode used in power electronics circuits, capable of handling...
