LATEST FEATURE: Finding the Right Technology to Solve Datacenter Power Challenges - Nov/Dec 2022 Read PDF
Although Silicon (Si) is the most familiar technology, its smaller bandgap limits operating temperature, its low breakdown electric field restricts its use to lower voltages, and its low thermal conductivity limits power density compared to wide bandgap (WBG) materials, like gallium nitride (GaN) and Silicon Carbide (SiC). Digitization and the rapid deployment of cloud services have boosted the growth of datacenters worldwide. WBG helps to reduce their power consumption.
