This book is dedicated to field emission electronics, a promising field at the interface between “classic” vacuum electronics and nanotechnology. It particularly focuses on research into and production of field cathodes and electron guns using recently developed nanomaterials and carbon nanotubes.

This book is dedicated to field emission electronics, a promising field at the interface between “classic” vacuum electronics and nanotechnology. In addition to theoretical models, it includes detailed descriptions of experimental and research techniques and production technologies for different types of field emitters based on various construction principles. It particularly focuses on research into and production of field cathodes and electron guns using recently developed nanomaterials and carbon nanotubes. Further, it discusses the applications of field emission cathodes in new technologies such as light sources, flat screens, microwave and X-ray devices.
