Single-crystal diamond has extremely good thermal conductivity — almost five times that of a SiC substrate — and can efficiently spread heat. In order to bond a single-crystal diamond to a device as a cooling material, normal production processes use an argon (Ar) beam to remove impurities, which produces a low-density damaged surface that weakens the bonds the single-crystal diamond can form.
