Vinod Kumar Khanna: Field-Emission Vacuum Nanoelectronics, Gebunden

Klappentext

FieldEmission Vacuum Nanoelectronics: A Bird's Eye View of Theory and Practical Applications explores the field in both theoretical and practical perspectives. Fieldemission devices have moved from specialized applications to become potential candidates for a future beyondcomplementary metaloxidesemiconductor (CMOS) circuits, offering superior performance at extreme temperatures, in harsh environments, and at high frequencies, due to their reliance on ballistic transport in vacuumlike or nanogap airfilled environments rather than solidstate lattice transport.

Beginning with the mechanisms of electron emission from materials and highlighting the role of nanotechnology in field emission, the Fowler-Nordheim theory of field emission is extensively treated. Enhancements of the Fowler-Nordheim theory and its various alternatives are addressed, with emphasis on the Schottky-Nordheim transmission barrier, the Murphy-Good theory, and efforts made to rephrase and reformulate the standard Fowler-Nordheim theory. On the practical side, the key components of fieldemission devices, namely, cold cathodes, arrays, and electron guns, are described. Applications covered include fieldemission displays and lamps, diodes and transistors, microwave power tubes (magnetrons, gyrotrons, klystrons, and travelingwave tubes [TWTs]), information storage devices, sensors, electron microscopy, spectroscopy, scanning probe lithography, Xray tubes, electric propulsion thrusters, and charge neutralizers. This book concludes with a discussion of research challenges and the future outlook for fieldemission nanoelectronics. This book will be immensely useful to graduate and research students, engineers, and scientists.
