Abstract
The dielectric functions of biaxial α-SnS at temperatures from 27 to 350 K are modeled with an analytic expression for Tauc-Lorentz oscillators. The temperature dependence of all the obtained parameters are fitted to third-order polynomial equations. The results provide a comprehensive database of the coefficients, which allows the construction of the dielectric function of biaxial α-SnS at arbitrary temperatures from 27 to 350 K and in the spectra range from 0.73 to 6.0 eV, which can be converted to optical constant values such as refractive indices and the absorption coefficients along the armchair-, zigzag-, and c-axes directions for designing optoelectronic devices based on the SnS material.
