Abstract
Heterojunctions have received much interest as a way to improve semiconductors' electrical and optical properties. The impact of the interface on the electrical and optical properties of g-C(3)N(4)/SnS(2) was explored using first-principles calculations in this study. The results show that, at the hetero-interface, a conventional type-II band forms, resulting in a lower band gap than that in the g-C(3)N(4) and SnS(2) monolayers. When there is no high barrier height, the averaged microscopic and averaged macroscopic potentials can be used to accomplish efficient carrier transformation. Furthermore, the polarization direction affects the absorption spectra. All of these discoveries have significant implications for the development of g-C(3)N(4)-based optoelectronics.
