Summary:Electron transport in mesoscopic systems provides a theoretical basis for the design of nanoscale nanostructured electronic devices. Based on the transmission matrix method proposed in previous research, the transmission coefficient of the cross-type four-terminal quantum dot array system model is calculated, and the four-terminal system model is converted into a two-terminal model, and the electron transport relative to the asymmetrical and symmetrical cross-type quantum dot array system at the intermediate origin is studied. The results show that the number of transmittance spikes of the spatially inverted symmetrical cross-shaped quantum dot array is equal to the number of quantum dots on the quantum dot array, and the transmission coefficient is related to the energy of the incident electron, the width of the quantum dots and the number of quantum dots, and is not related to the transition integral.
