Theoretical Modeling of UV Photoelectron Emission Yield of Spacecraft Surface Materials

Spacecraft surface materials, Photoelectron Emi-ssion Yield (PEEY), Quantum Efficiency (QE), Theoretical Models, Three-step emission theory

The purpose of this paper is to introduce the research progress on the theoretical modeling of photoelectron emission yield (PEEY) of spacecraft surface materials. The article mainly introduces the development of PEEY theoretical models, including FD model, one-step model, TSM model/MC model based on three-step emission theory, and MFD model, MB model (Moments-based, MB) and quantum model. Then we analyze and compare the research methods and applicable conditions of each model to sort out the developmental lineage of PEEY model.
