摘要：

We calculate the dynamical dielectric function of doped double-layer graphene (DLG), made of two parallel graphene monolayers with carrier densities n(1) and n(2), and an interlayer separation of d at finite temperature. The results are used to find the dispersion of plasmon modes and loss functions of DLG for several interlayer separations and layer densities. We show that in the case of n(2)=0, the finite-temperature plasmon modes are dramatically different from the zero-temperature ones. (C) 2013 Elsevier B.V. All rights reserved.
