High temperature diamond thin film for capacitor applications

Diamond has some excellent electrical and thermal properties which make it an attractive choice for high temperature, high energy density capacitor applications. Diamond has a very high voltage breakdown strength, a relatively high dielectric constant coupled with the highest thermal conductivity known to mankind. Diamond is also chemically inert, and radiation hard with zero toxicity. This research activity describes and compares capacitors fabricated using polycrystalline diamond, diamond-like carbon films (amorphous diamond), natural diamond and synthetic diamond.<>
