Enhanced visibility of graphene: Effect of one-dimensional photonic crystal
Abstract
We investigate theoretically the light reflectance of a graphene layer prepared on the top of one-dimensional Si /SiO2 photonic crystal (1DPC). It is shown that the visibility of the graphene layers is enhanced greatly when 1DPC is added, and the visibility can be tuned by changing the incident angle and light wavelengths. This phenomenon is caused by the absorption of the graphene layer and the enhanced reflectance of the 1DPC.
