Optoelectronic properties and interfacial interactions of two-dimensional CsPbX-MSe (M = Mo, W) heterostructures.

Constructing 2D inorganic perovskites and TMDs heterostructures is an effective method to design stable and high-performance perovskites optoelectronic applications. Here, we investigate the optoelectronic properties and interfacial interactions of CsPbX-MSe (X = Cl, Br, I; M = Mo, W) heterostructures using first-principles calculations. Firstly, six CsPbX-MSe interfaces remain stable in energy.
