10 Things to Know about GaN
By Stefano Lovati, Power Electronics News
Wide bandgap materials such as?gallium nitride (GaN)?are emerging as the technology to take electronic performance to the next level.?GaN-based electronic components offer a number of important advantages over silicon devices, including more compact size, higher power density, higher efficiency, lower switching losses, and better thermal management. These factors are critical to meeting the increasingly stringent requirements associated with high-power and high-density applications, such as converters, inverters, radio frequency (RF) devices, amplifiers, power supplies and chargers.
10 Things to Know About SiC
By Stefano Lovati, Power Electronics News
Silicon carbide (SiC), a semiconductor compound consisting of silicon (Si) and carbon (C), belongs to the wide bandgap (WBG) family of materials. Its physical bond is very strong, giving the semiconductor a high mechanical, chemical and thermal stability. The wide bandgap and high thermal stability allow SiC?devices to be used at junction temperatures higher than those of silicon, even over 200°C. The main advantage offered by silicon carbide in power applications is its low drift region resistance, which is a key factor for high-voltage power devices.
SiC-based power devices are driving a radical transformation of power electronics, thanks to a combination of excellent physical and electronic properties. Although the material has been known for a long time, its use as a semiconductor is relatively recent, in great measure due to the availability of large and high-quality wafers. In recent decades, efforts have focused on developing specific and unique high-temperature crystal growth processes.
