Abstract: (1671 Views)
Nowadays, two-dimensional materials MoS2 have received a lot of attention due to its high absorption despite their nanometer thickness. One of the most common methods to increase absorption is to insert monolayer MoS2 as a defect in photonic crystals. In this paper the absorption spectrum of the structures antisymmetric and symmetric defective photonic crystals with two different defects (DMD and MDM) are compared. The influences of altering the thickness of defect layer D on wavelength of defect mode are investigated. Transfer matrix method is used to calculate absorption. More than 93 percent absorption in design wavelength and near 90 percent in wavelength of edge band gap could be obtained by proposed structures.
Keywords: Absorption, Defective photonic crystal, Mobilidium disulfate, Two-dimensional materials, Transfer matrix method.
