Abstract: (1394 Views)
Today, two-dimentional materials such as MoS2 have exhibited distinctive capabilities in optoelectronic applications. In this paper,to achieve high absorption and wavelength-adjustable, defective photonic crystals is used which is formed of {(AB)p MDM (AB)q}that p and q show the number of alternation for top and bottom defect layer which is selected as MoS2/D/MoS2. The transfer matrix method is used to determine absorption. Also, optimal structure is found by changing the number of p, q and thickness of D. Near perfect absorption, which is more than 97 percent, with wavelength-adjustable capability could be obtained by proposed structure. By enhancing the thickness of D, red shift is resulted in wavelength of defect mode.
