Basic Principles of Electronics, Volume I: Thermionics covers topics related to thermionic devices. The book starts by providing a physical background about electronics, including structure of matter, ionic, chemical and covalent combination, crystalline structure, conductors and insulators, and thermionic emission. The text then discusses electron dynamics; the characteristics and properties of electrons in solids; electron emission; and thermionic emission in a vacuum diode or triode. The development of the vacuum triode; gas-filled valves; and power amplifiers are also considered. The book further tackles oscillators intended to give a sinusoidal output as well as electronic measuring equipment. Students taking electronics for physics courses will find the book useful.
