We devise a simple heuristic method for obtaining the relaxation time and electrical conductivity dependence on the temperature of carriers in 2D semiconductors. trace. One of the most typical uses of BoltzTraP is the calculation of thermoelectric transport coefficients as functions of temperature and chemical potential in the rigid-band picture. It is based on a smoothed Fourier interpolation of the bands. Topics In this paper, we established a multi-cell model of BNNRs, and the theoretical modeling and performance simulation of BNNR transport properties and thermoelectric coefficients were carried out using the Vienna ab initio simulation package (VASP) and BoltzTrap first-principles calculation to explore the quantum size effect.
