Latest Patents
Krohn holds a patent for "Surface-emission cathodes having cantilevered electrodes." This invention describes a surface-emission cathode formed on an insulating surface with cantilevered, or 'undercut,' electrodes. The suitable insulating surfaces for this technology include negative electron affinity (NEA) insulators such as glass or diamond. The cathode is designed to operate in a compromised vacuum, such as 10 Torr, without requiring bias on the electrodes and can function effectively under low vacuum electric fields, typically at least 10 V/cm. The fabrication process is cost-effective, requiring lithographic resolution of approximately 10 micrometers. This technology can be applied over large areas, making it ideal for lighting and display applications, as well as satellite uses, including cathodes for tethers, thrusters, and space-charging neutralizers. Krohn has 1 patent to his name.
