Abstract
MoS2 has attracted considerable attention owing to its unusual and intriguing potential applications in optoelectronic devices. In this study, the absorption properties of a simple one-dimensional (1D) layered structure composed of monolayer MoS2 are analyzed by transfer matrix method. The dielectric permittivity of monolayer MoS2 is employed using the Lorentz model. The influences contributed to the period of the structure and the incident angle are numerically investigated. Our results indicate that a tunable multi-band (broadband) absorber can be achieved by using such a 1D layered structure. A multi-band (broadband) absorption phenomenon can be obtained by increasing the period of the structure. Furthermore, the absorption peaks and broadband absorptance spectra have blue-shifted as the incident angle increases.
