Thermionic emission is the emission of electrons from the surface of a metal or other conductive material due to the application of sufficient thermal energy. This phenomenon plays a critical role in vacuum tubes, cathode ray tubes, and certain types of diodes and transistors. Thermionic emission occurs when electrons acquire kinetic energy exceeding the work function of the heated metal surface, enabling them to escape the material. History Thermionic emission was first observed in the late 19t
