(a) Temperature dependence of zT for the SnS films deposited at 397, 418, and 445 °C. (b) Comparison of zT in this work (red stars) with reported values for SnS bulks with similar grain size to that of our SnS film, and SnSe and SnS thin films (star symbols) prepared by low-cost deposition techniques.^{11,18,63−65}
