Series and parallel models render 39]: (i) the electrons and phonons of the metal couple with one thermal conductivity of 200 Wm 1K 1 and 900 Wm 1K 1 for another, and the energy can be transferred ... Web(see, e.g., Refs. 15–18), and in the context of graphene, plasmons were shown to couple to surface optical phonons of the substrate (e.g., SiC, which is a polar material).11 ,19 20 Here we predict the coupling of plasmons with intrinsic optical phonons in graphene by using the self-consistent linear response formalism. We find that, in ...
