Transient Characteristics of The Transport Process of Non-Equilibrium Carriers With High Electric Field |
| |
| Abstract: | According to the quantum statistical theory, combining with the lattice structure of material and band characteristics, a detailed study was performed on the microstructure of electronic states of semiconductor material and the quantum statistical distribution characteristics of non-equilibrium carriers. The microstate and relaxation process of the electron-phonon interactions were analyzed. The nonlinear characteristics and transient characteristics of distribution function, relaxation process and transport process of non-equilibrium hot electrons under high electric field were studied, and the microscopic interactions and transient transport mechanism of non-balanced hot electrons were revealed. |
