Abstract:
The structural and physicochemical properties of the MoSe2/PTCDA heterostructure, which consists of two-dimensional inorganic and molecular organic semiconductors, have been studied theoretically. Features of change in the electronic properties of the PTCDA monomolecular layer on the MoSe2 surface have been described by density functional theory. The quantitative analysis of charge transfer between the heterostructure components has explained the features of coupling between the layers. The study of the optical characteristics of the heterostructure has revealed the enhancement of the absorption spectrum in the infrared range. Consequently, MoSe2/PTCDA heterostructures are promising for applications in electronics, optoelectronics, and materials for the utilization of solar energy.
