Megawatt auto-emission electronic devices

The possibility of creating on the basis of the inverse piezoelectric effect and the negative electronic affinity of nanodiamonds (which is the natural state of the surface 111) auto-emission devices of megawatt output power operating in the key mode is considered. A comparison of two principles of operation of auto-emission devices based on a change in the field between the cathode and the anode is given. It is shown that explosive emission limits the possibility of obtaining megawatt power by changing the voltage, and also that a more promising method is to control the field by changing the cathode–anode distance from tens of nanometers to microns. Estimates are given according to which such a device has a high efficiency and can operate at a pressure of the order of atmospheric pressure.
