AB  - In our previous publications [1-4] we studied the effects of plasmon-phonon hybridization in graphene supported by an insulating substrate [1], as well as in graphene-insulator-graphene composite systems [2-4]. In this work we investigate the hybridization between the Dirac plasmon in graphene layer biased with a drift electric current and the surface optical phonon modes in the insulating substrate. The dielectric function of the system is written in terms of the response function of graphene and the bulk dielectric function of the substrate. The response function is expressed in terms of a nonlocal conductivity of graphene. The intraband conductivity of graphene is obtained using the Boltzmann theory [5-6], whereas the effects of high-energy interband electron transitions are accounted for by using a linear function of frequency for the imaginary part of the interband conductivity [7]. The conductivity with a drift current is evaluated using the Galilean Doppler shift model [8,9]. The energy loss function (the imaginary part of the negative value of the inverse dielectric function) is presented for three different values of the drifting velocities of electrons showing the effects of the drift velocity on the plasmon-phonon hybridization.
