Applications of Electron Emission Physics
暫譯: 電子發射物理學的應用

From theory to device construction in electron emission technology

Constructing, modeling, and operating electron emission devices demands a command of both underlying physics and practical engineering realities. Applications of Electron Emission Physics is written by Kevin L. Jensen, an APS Fellow, a recipient of the Sigma Xi Applied Science Award for his work on electron emission, a research physicist at the Naval Research Laboratory, and now at the University of Maryland. He delivers field-tested concepts for the modeling and simulation of electron sources, particularly those based on thermionic, field, and photoemission, grounded in decades of hands-on research and instruction experience.

Applications of Electron Emission Physics covers the use of electron emission theory and models to the understanding and operation of electron emission devices alongside a detailed treatment of electron beam physics. The text provides algorithms needed to simulate theoretical models and interpret experimental results obtained with both lab-scale and large-scale electron sources. Included code algorithms enable readers to perform their own numerical computations, analyze data, simulate, and validate experimental observations against theoretical predictions.

Readers will also find:

• Field-tested methods for simulating quantum mechanical tunneling and emission, and modeling electron sources modified by changes to materials, emitter shape, and the application of coatings
• A detailed overview of electron beam physics connecting source design to downstream beam transport and performance
• Algorithmic tools for interpreting experimental results from both laboratory-scale and large-scale electron source configurations
• Code algorithms enabling independent numerical computation, data analysis, simulation, and direct comparison of theory with experiment
• Practice-oriented guidance shaped by the author's extensive research at both the Naval Research Laboratory since 1990 and the University of Maryland since 2023

Designed for advanced graduate students, PhD candidates, academics, and researchers in solid state physics, materials science, electron transport, and beam physics, this book serves both users and developers of electron sources who require a unified treatment connecting emission theory directly to device construction, operation, and experimental analysis.
