Power electronics is the branch of electronics that deals with collecting, delivering, and storing energy, by conversion and control of electrical power. While silicon has been traditionally used for power electronics, it no longer is able to keep up with the evolving requirements of higher efficiency, smaller size, and greater reliability. Enter wide bandgap materials. Researchers are now focusing on materials such as gallium nitride (GaN) and silicon carbide (SiC) to replace silicon for power electronics applications. The articles in the May issue of MRS Bulletin overview research on GaN and SiC for power electronics, and the talks presented in this webinar are representative examples of the research detailed in this issue.
