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.

双轴 α-SnS 介电函数的温度依赖性建模

双轴 α-SnS 在 27 到 350 K 的温度下的介电函数使用 Tauc-Lorentz 振荡器的解析表达式进行建模。所有获得的参数的温度依赖性都适合三阶多项式方程。结果提供了一个全面的系数数据库，允许在 27 到 350 K 的任意温度和 0.73 到 6.0 eV 的光谱范围内构建双轴 α-SnS 的介电函数，可以将其转换为光学常数值例如用于设计基于 SnS 材料的光电器件的沿扶手椅、锯齿形和 c 轴方向的折射率和吸收系数。
