SPATIAL DISTRIBUTION OF ELECTRON ENERGY IN THIN FILM ELECTROLUMINESCENT DEVICES
薄膜电致发光器件电子能量的空间分布

We adopted an analytical approach based on fitting of the full band structure of ZnS by polynomials.We studied the electron transport process in phosphor layer of thin-film electroluminescent divices by Monte Carlo Simulation.Two kinds of spatial distributions of electron energy are obtained in phosphor layers of the sandwich structure and the layered optimization structure,and the explanation about it is also given.
