A Detailed Description of Keldysh's Model of Photoionization
Author
Darden, Kenan
Date Created
2023
Subjects--Topical
Physics, Optics, Quantum theory
Description
Leonid Keldysh’s 1965 paper "Ionization in the Field of a Strong Electromagnetic Wave" contains useful and simple-to-implement equations predicting the rate of photoionization in both atomic gasses and general crystalline solids. Crucially, his re...
