Abstract: ELECTRON-PHONON INTERACTION (EPI) CONTRIBUTES ONE OF THE MOST IMPORTANT SCATTERING PROCESSES FOR ELECTRONIC TRANSPORT IN NANOSTRUCTURE. IN THIS THESIS, WE THEORETICALLY INVESTIGATE THE MECHANISM AND CONSEQUENCE OF EPI ON THE QUANTUM ELECTRON AND HEAT TRANSPORT IN NANO-JUNCTION, FOCUSING ON THE STRONG EPI STRENGTH REGIME. IN STEADY STATE TRANSPORT, WE WILL ANALYZE THE EPI-INDUCED TRANSPORT PROPERTIES SUCH AS PHONON ASSISTED TUNNELING AND NEGATIVE DIFFERENTIAL RESISTANCE. WE ALSO EXPLORE THE INFLUENCE OF EPI ON THE THERMOELECTRIC TRANSPORT OF THE SYSTEM AND FIND THAT EPI CAN DRASTICALLY DESTROY THE THERMOELECTRIC EFFICIENCY. WE INVESTIGATE THE LOCAL HEATING CAUSED BY EPI SCATTERING AND FIND THAT SUCH HEATING IS POSSIBLE TO BE ELIMINATED IN THERMOELECTRIC TRANSPORT. WE THEN GO FURTHER TO STUDY DRIVEN SYSTEMS WITH EPI, UPON THAT WE ESTABLISH A DYNAMIC THERMOELECTRIC THEORY. WE FIND THAT THERMOELECTRIC EFFICIENCY CAN BE GREATLY BOOSTED UNDER TIME-DEPENDENT CONTROL, WITH THE REASON ROOTING
