Abstract

Analytical results for plasmon excitations are quite unpopular because of the complicated polarizality functions. This paper presents the analytical calculations for plasmon frequencies in long wavelength limit of a double layer made of bilayer graphene and GaAs quantum well. Calculations are done with taking account of electron gas layer thickness and background dielectric constants inhomogeneity, based on polarizality functions in random phase approximation. Results illustrate that the optical frequency is similar to that obtained in previous researches, while the acoustic one is affected by both the distance between two layers and 2DEG layer thickness.
