Field Emission,e with thermionic emission, photoelectric emission, or secondary emission. From the standpoint of technical significance, field emission ranges definitely as the last one. This is due to technical difficulties still arising in the application of extremely high fields. However, the theoretical unders广口瓶 发表于 2025-3-25 17:03:49

Photoionization in gases and photoelectric emission from solids,city, and the ionospheric layers at high altitudes. In addition laboratory studies on the conduction of electricity through gases frequently must concern themselves with the participation of photons in certain events. In each case the individual problems differ widely, and of all processes by whichIrascible 发表于 2025-3-26 03:23:01

Thermionic Emission,r particles that may carry with them either a net positive or a net negative charge. Since these phenomena are so very different basically, this article will be devoted exclusively to the more fundamental aspects of the experimental and the theoretical investigations of the phenomenon of . emission from heated conductors.
