Cold cathodes were originally described in the 1960s, when it was recognized that they represented an elegant and efficient electron source. For more than 50 years, numerous groups around the world have attempted to engineer cold cathodes that would withstand a harsh high voltage environment and which had the requisite power density to compete with traditional hot cathodes.
Nanox field effect cathode technology was originally developed for use in high-definition flat panel displays. Over time, the manufacturing processes were ported from glass to silicon, enabling enormous increases in power density and uniformity. After more than 20 years of research and development, with over $1B invested, our team of engineers has developed unique intellectual property, patents, and capability to design and build high-powered field effect cathodes that outperform all previous efforts.
