Abstract: (1397 Views)
In this paper, reflection, Kerr rotation and ellipticity spectra of a three layered structure constitiuted of Graphene, Silicon Carbid, and Aluminium were studied in terehertze frequency region. Using 4×4 transfer matrix method the spectra of Graphene/SiC structure were calculated and compared with the spectra of Graphene/SiC/Al structure. The results show that both reflection spectra have resonance behaviors. But, in the structure containing the Al, the reflection values at similar frequencies are different. Moreover, resonance behavior in Kerr rotation and ellipticity spectra were seen for both of the structures, inwhich by using the Al layer their maximum values were changed. Also, by increasing the external magnetic field strength, behavior of Kerr rotation and ellipticity spectra were changed.
