Gallium nitride can conduct thousands times more power than silicon and Gallium Nitride (GaN) is a wide band-gap (WBG) semiconductor material, and like silicon, GaN can be used to make semiconductor devices such as diodes and transistors. A power supply designer would choose a GaN transistor instead of silicon if they were targeting a small form factor and high efficiency. Who’s Who In Silicon Carbide And Gallium Nitride Power Semiconductors by David G. Morrison, Editor, How2Power.com This document offers a listing of manufacturers of silicon carbide (SiC) and gallium nitride (GAN) discrete power semiconductors, ICs and modules as well as companies providing related foundry services. Descriptions of each Silicon carbide (SiC) and latest gallium nitride (GaN) are two semiconductor materials which entered the power device arena which has been set up and still is being dominated by silicon based devices. The following paper will make a basic comparison of power devices out of these three base materials valid for medium voltage classes of some hundred to above 1000V. This paper will start with Performance of Wide-Bandgap Gallium Nitride vs Silicon Carbide Cascode Transistors. October 2020; DOI: 10.1109/ECCE44975.2020.9236187.

A power supply designer would choose a GaN transistor instead of silicon if they were targeting a small form factor and high efficiency. CoolGaN™ - bringing Gallium Nitride (GaN) technology to the next level GaN has an even higher bandgap (3.4 electronvolt) and substantially higher electron mobility than SiC. Compared to silicon (Si), the breakdown field is ten times higher and the electron mobility is double. The leading candidate for taking electronic performance to the next level and a reactivation of positive momentum of Moore’s Law is gallium nitride. GaN’s ability to conduct electrons more than 1000 times more efficiently than silicon , while being able to be manufactured at a lower cost than silicon has now been well established.

The Gallium nitride crystals’ electrons can move 30% faster than silicon's electrons. This electron mobility offers GaN an undeniable advantage in higher switching frequencies. applications are Gallium Nitride (GaN) and Silicon Carbide (SiC). There is a great deal of on-going discussion and questions about Gallium Nitride (GaN) versus Silicon Carbide (SiC) material, the semiconductor devices which are possible and which device / material is best suited for various switching and RF power applications. Gallium nitride and silicon carbide have long been attractive alternatives to silicon in power electronics: they’re capable of faster switching speeds and can handle a higher voltage than a same It is possible to grow gallium nitride crystals on top of silicon, so they can be produced in existing silicon manufacturing facilities and do not require costly specialized production sites. Although gallium nitride crystals are currently still more expensive to produce than silicon, GaN semiconductors lower a system’s overall production costs by reducing the size and cost of other components.
