Silicon carbide nanosheets (SiCNSs) have broad application prospects in nanoscale electronic devices. Therefore, the study of its transport properties is of great importance. The traditional two-dimensional (2D) transport model considers that all carrier scattering is confined to the thin layer, that is, there is only one single transport channel (STC). This STC model can simulate the transport properties of single-layer SiCNSs well, but there is a large error when simulating the few-layer SiCNSs (FL-SiCNSs). In this paper, we propose a dual transport channel (DTC) model based on the lattice structure and carrier distribution characteristics of SiCNSs and simulate the temperature and layer dependent of the conductivity, carrier concentration and mobility of FL-SiCNSs. The calculation results show that the room temperature conductivity of FL-SiCNSs is in good agreement with the experimental values, indicating that the DTC model can be used to complement low-dimensional semiconducting transport theory. The carrier transport mechanism of FL-SiCNSs is revealed in this paper, and the research can provide a theoretical basis for the application of 2D-SiC in the field of nanoelectronics.
