| description | In this paper, we explore the linear response of one dimensionalquasiperiodic structure based on Fibonacci sequence composed of silicon dioxide,polystyrene and graphene materials. Here, a graphene monolayer is sandwichedbetween two adjacent layers. The numerical results are obtained by using the standardtransfer matrix method. Due to the presence of graphene sheet in each structure, in theinitial range of THz, an additional gap GPBG is induced which is absent in the case ofwithout graphene. The amplitude of absorption peaks at the upper edge of the GPBGsignificantly enhances, when damping factor increases. The height of the absorptionpeak at the GPBG edge goes up as the temperature increases. At the GPBG edge, withincreasing the thickness of graphene, the absorption peak rises and shifts to the lowerfrequencies. Moreover, we have realized that the amplitude of absorption peaks at theupper edge of the GPBG significantly enhance by increasing damping factor. |
