Why is it important?
Wide- and ultrawide-bandgap semiconductors (GaN, boron nitride (BN), SiC, Diamond, and Ga2O3) are the heart of next-generation electronic industry due to their low power loss, higher operating voltage and temperature, and extreme environment applications as compared to conventional semiconductors such as Si, and GaAs. In addition, heterojunctions between these materials are of great significance for electronic devices as they can modify and/or further improve nanoscale device performance by utilizing the unique advantages of high breakdown electric field, increasing thermal conductivity, thereby improving the reliability of the device at extreme conditions.
