Abstract
Two-dimensional (2D) semiconducting tin disulfide (SnS2) has been widely used for optoelectronic applications. To functionalize SnS2 for extending its application, we investigate the stability, electronic and magnetic properties of substitutional doping by high throughput first-principles calculations. There are a lot of elements that can be doped in monolayer SnS2. Nonmetal in group A can introduce p-type and n-type carriers, while most metals in group A can only lead to p-type doping. Not only 3d, but also 4d and 5d transition metals in groups VB to VIIIB9 can introduce magnetism in SnS2, which is potentially applicable for spintronics. This study provides a comprehensive view of functionalization of SnS2 by substitutional doping, which will guide further experimental realization.
