Latest Patents

One of his latest patents is focused on polycrystalline III-nitrides. This invention provides a process for producing high-purity dense polycrystalline III-nitride slabs. A vessel containing a group III-metal, such as gallium or an alloy of group III-metals, is placed in a reactor. The group III-metal or alloy is heated until it reaches a molten state, after which a halide-containing source mixed with a carrier gas and a nitrogen-containing source is flowed through the reactor vessel. An initial porous crust of III-nitride forms on the surface of the molten III-metal or alloy, which reacts with the nitrogen-containing source and the halide-containing source. The flow rate of the nitrogen-containing source is then increased and flowed into contact with the molten metal to produce a dense polycrystalline III-nitride. The products produced from this inventive process can be used as source material for III-nitride single crystal growth, which material is not available naturally.

Another significant patent by Wang involves hydrothermal methods of fabricating trivalent-metal-ion-doped sapphire crystals. This method synthesizes sapphire single crystals doped with trivalent metal ions in a crystal-growth autoclave, which includes a crystal-growth zone and a nutrient-dissolution zone in fluid communication with the crystal-growth zone. The method situates at least one sapphire-based seed crystal within the crystal-growth zone and an aluminum-containing material within the nutrient-dissolution zone to serve as nutrient. An acidic, trivalent-metal-ion-containing growth solution is introduced into the cavity in a quantity sufficient to immerse the seed crystal and the nutrient in the growth solution when heated to a predetermined average temperature. The growth process is carried out while maintaining specific pressure and temperature differentials to ensure optimal crystal growth.
