ABSTRACT:
Diamond and diamond-like materials having photochemically modified surfaces, and a process for photochemically modifying the surface of diamond and diamond-like materials. Preferably, the substrate to be modified is a single crystal, polycrystalline film or powder of diamond or any silicon carbide polytype. Photochemical modification of the surface enables the addition or exchange of specific surface functional groups. These surface modifiers change the chemical, adhesive and electronic properties of the diamond and diamond-like substrate materials. The modified subtrates are useful for producing semiconductor devices for use at high temperatures, high powers, and in otherwise harsh environments.
