The diamond for power electronic devices

Diamond has the most interesting and extreme thermal, dielectric and electronic properties of semiconductors. The benefits of using diamond for power electronic switch can be illustrated by a new figure of merit. The exploration of possible device applications for this material has been motivated by the significant advances in growth and electronic technologies of diamond. Our studies are focused on two specific problems of power electronic: thermal management and high voltage switching. Indeed, diamond exhibits a unique combination of the highest electric breakdown field and thermal conduction that make it a potential candidate for power electronic packaging. Moreover, recent improvements in single crystal diamond growth have resulted in films with very high carrier mobility and high electric breakdown field that present a new interest for high power switches.
