Yogesh Vohra, Ph.D., has gained national and international recognition for his work with synthetic diamonds and the application of synthetic diamond technology in high-pressure research. His research focuses on the microwave plasma processing of materials, high-pressure phenomena in materials, superhard materials and coatings for industrial applications, the growth and characterization of synthetic diamonds, laser diagnostics methods in materials research and diamond coating for machine tools, aerospace components and biomedical implants. He patented a process in May 1997 to grow synthetic diamonds by combining methane and hydrogen gases with high-powered microwaves and depositing diamond crystals on a seed crystal at 1,200 degrees Celsius. Most recently, in February 2001, Vohra and UAB researcher Shane Aaron Catledge were issued a patent for a process they developed that uses a microwave plasma chemical vapor deposition method to modify the chemistry of a plasma process while in the growth chamber to produce the smooth film called nanostructured diamond films that is deposited on metals. Vohra has published more than 125 articles in referred journals in physics and materials science including Matter, the Journal of Applied Physics, the Journal of Crystal Growth and Physics Review. He is a professor of physics.
