Theoretical Modeling for UV Photoelectron Emission Yield of Spacecraft Surface Materials

The purpose of this paper is to introduce the research progress on the theoretical modeling for photoelectron emission yield (PEEY) of spacecraft surface materials. The article mainly introduces the development of PEEY theoretical models, including FD(Fowler-DuBridge) model, one-step model, TSM(Three-step model) IMC(Monte carlo) model based on three-step emission theory, MB(Moments-based) model 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.
