TLDR
In this paper, the authors investigate the plasmon frequency and decay rate in a double bilayer graphene (DBLG) heterostructure made of two bilayer GAs separated by a spacer of thickness d. Calculations are carried out at zero temperature, within the random phase approximation, taking into account the inhomogeneity of the dielectric background of the system.About:

Plasmon modes in N-layer bilayer graphene structures
TL;DR: In this paper, the authors calculate the plasmon frequency and broadening function in a system consisting of N, up to 5 bilayer graphene sheets at zero temperature, and find that there are one in-phase optical mode and N-1 out-of-phase acoustic ones in plasmor dispersions of the system.

Collective excitations in gapped graphene-GaAs double-layer structures
TL;DR: In this article, the collective excitations and decay rate of plasma oscillations in a gapped graphene-GaAs double-layer structure within random phase approximation without temperature effects were determined. And the analytical formulae demonstrate that the band gap has significant contributions to collective excitation.
