Abstract
We present theoretical study on developing a one-dimensional (1D) photonic crystal heterojunction (h-PhC) that consists of a monolayer molybdenum disulfide (MoS2) structure. By employing the transfer matrix method, we obtained the analytical solution of the light absorption and emission of two-dimensional materials in 1D h-PhC. Simultaneously enhancing the light absorption and emission of the medium in multiple frequency ranges is easy as h-PhC has more modes of photon localization than the common photonic crystal. Our numerical results demonstrate that the proposed 1D h-PhC can simultaneously enhance the light absorption and emission of MoS2 and enhance the photoluminescence spectrum of MoS2 by 2–3 orders of magnitude.
Highlights
Two-dimensional (2D) transition metal dichalcogenides (TMDCs), such as MoS2 and WSe2, are direct-gap semiconductor 2D materials with excellent optical properties and are considered one of the best materials for future optoelectronic devices[1,2,3,4,5,6,7]
To further enhance the light emission and absorption of 2D TMDCs, we investigated the effect of photonic crystal heterojunction (h-photonic crystals (PhC)) on the light absorption and emission of MoS2
We calculated the positive incidence of the pumping light and the absorption and relative radiation intensity of MoS2 when the pumping and outgoing lights are on opposite sides of the h-PhC
Summary
Two-dimensional (2D) transition metal dichalcogenides (TMDCs), such as MoS2 and WSe2, are direct-gap semiconductor 2D materials with excellent optical properties and are considered one of the best materials for future optoelectronic devices[1,2,3,4,5,6,7]. The analytical solution can be used for the light absorption and emission in h-PhC and for the calculation of other 1D PhC-2D materials composite structures.
