Gallium nitride (GaN) and silicon carbide (SiC) will displace silicon (Si) in power conversion due to higher performance and lower cost. GaN and SiC will service different segments of the market. GaN will take over consumer, telecom, and computer appliions, while SiC will be most prominent in industrial appliions that require higher voltages and current.

Hence, we have obtained the most stable configurations, interstitials in a perfect crystal and complexes in presence of mono and divacancies, as well as their formation energies. In a second step, our simulations have allowed us to determine the migration mechanisms of noble gas interstitials and of complexes, and the associated activation energies, in the case of silicon.
