Abstract: (808 Views)
In this paper, we have analytically investigated the effects of temperature and electric field perpendicular to the silicene surface on the transverse electric wave propagation range in the frequency range of 1 to 30 THz. Unlike graphene, the atomic structure of a silicene composite is not flat, which makes the surface conductivity of silicene, in addition to the Fermi level, adjustable with an electric field perpendicular to the silicene surface. This property allows silicene to emit transverse electric waves over a wider range than graphene. According to the simulation results based on Kubo equations, per vertical electric field of 100 mV/Å, the propagation bandwidth of TE waves at temperatures of 5 K, 100 K, 200 K and 300 K are equal to 9.2 THz, THz 8, 1.3 THz and 0.9 THz, respectively. By increasing the vertical electric field to 200 mV/Å, the bandwidth for these temperatures will be 20.7 THz, 20.6 THz, 16.7 THz and 11.7 THz, respectively. In the vertical electric field to 300 mV/Å, these values are 29 THz, 28.8 THz, 26.4 THz and 21.8 THz, respectively. The confinement length of TE waves in the propagation ranges has also been obtained, which has increased the trapping length with increasing temperature.
