This technology was later licensed to and commercialized by SI Diamond Technology, Inc. (currently Nano-Proprietary, Inc.) with the help of Dr. Kumar, who led SIDT as the Director of Technology. He was also the principal investigator for the $7.3 million diamond cold cathode based display development project funded by Advanced Technology Program of the Department of Commerce, and the $1.0 million diamond material development program funded by Defense Advanced Research Projects Agency (DARPA).

Dr. Nalin Kumar, president of UHV Technologies, Inc., is the founder of NanoRanch. He has more than 20 years of experience in high technology R&D and product development, specifically silicon micro-nano-tips, nanocrystalline diamond and other wide bandgap cathodes.

After his doctoral work on development of titanium nitride thin films, he joined Microelectronics and Computer Technology Corporation (MCC) in Austin, Texas, a consortium of leading US companies. At MCC, he led the advanced materials projects for several years. Dr. Kumar’s work on nanocrystalline diamond field emitter flat panel displays, started in 1989 at MCC, led to the first and some of the most fundamental patents in this field. 


He is the inventor of the Amorphic Diamond electron emitter cathode and cylindrical magnetron plasma deposition system, and has 62 US patents in these areas.
