AB  - In our recent publication1 we have studied the wake potential induced by an external charged particle that moves parallel to various sy1-Al2O3-sy2 composites, where syi (with i=1,2) may be vacuum, pristine graphene, or doped graphene. Several important parameters were fixed at their respective typical values: the distance of the charged particle from the closest surface, the thickness of the sapphire (aluminum oxide, Al2O3) layer, and the doping density (i.e., Fermi energy) of graphene. In this work we present a detailed study of the effects due to variations of all those parameters in the case of the wake potential produced by charged particle moving parallel to the graphene-Al2O3- graphene composite system, by using the dynamic polarization function of graphene within the random phase approximation for its π electrons described as Dirac’s fermions and by using a local dielectric function for the sapphire layer2 . For the velocity of the charged particle below the threshold for excitations of the Dirac plasmon in graphene, given by its Fermi velocity vF, strong effects are observed due to variation of the particle distance, while for the velocity of the charged particle above vF strong effects are observed due to varying the thickness of the Al2O3 layer, as well as due to graphene doping.

AB  - We investigate the wake potential of different hybrid modes in the sy1-Al2O3-sy2 composites induced by charged particle moving parallel to the structure, as depicted in FIG. 1. This will be attained by exposing any wake patterns of the electrostatic potential in the surface closest to the incident particle. The three methods used in acquiring the effective dielectric function of the structure are based on the massless Dirac fermions (MDF), the extended hydrodynamic (eHD) model, and the ab initio approach. It is shown that in the low velocity regime (below graphene’s Fermi velocity, vF) transverse optical (TO) phonons in the Al2O3 layer give dominant contribution to the wake potential. In the intermediate velocity regime (above vF) it is the hybridized plasmon-TO phonon modes on both surfaces that give rise to the wake potential with hybridized Dirac plasmons giving the dominant contribution. For the high velocities (well above vF) only the symmetric hybridized Dirac plasmons are excited by the charged particle. It was found that ab initio approach agrees well with the MDF method at low and intermediate velocities for the pristine and doped graphene, and with eHD method at high velocities for pristine graphene layer

AB  - We study the wake effect induced by an external charged particle which moves above various sy1-Al2O3-sy2 composites, where syi (i=1,2) may be vacuum, pristine (undoped) or doped graphene. The polarization functions of graphene sheets are obtained using two approaches within the random phase approximation [1]: an ab initio method and a method based on the massless Dirac fermion approximation. The dynamic response of the layer of Al2O3 (sapphire) is described by a dielectric function consisting of several Lorentzian terms [1]. We evaluate the total electrostatic potential in the plane of the upper graphene sheet (the wake potential). It is shown that in the low velocity limit (below a velocity threshold for the wake given by the Fermi speed of graphene) the charged particle excites only the transverse optical (TO) phonons in the Al2O3 slab and only those phonons contribute to the wake potential. It is also shown that the wake potential is only sensitive on the upper system sy2 such that if sy2 is vacuum then TO phonons give intensive oscillations which are strongly reduced if sy2 is graphene.

AB  - We present an analytical modeling of the experimental electron energyloss(EEL)spectroscopy data for free-standing graphene obtained by scanning transmission electron microscope using a two-dimensional, two-fluid extended hydrodynamic (eHD) model and an ab initio method [1]. An analytical expression for the probability density for energyloss of fast electrons traversing graphene under normal incidence is derived in the long wavelength limit in terms of an arbitrary form of the conductivity of graphene given in the local, i.e., frequencydependent form. The calculated probability density from both theoretical modelsis directlycompared with the EEL spectra from three independent experiments [2-4] and we find verygood agreement, especially in the case of the eHD model. Furthermore, we point out that the method of subtraction of the zero-loss peak from the experimental EEL spectra maystronglyaffect agreement with analytical models.

The response function of each graphene is obtained using two approaches within the random phase approximation: an ab initio method that includes all electronic bands in graphene and a computationally less demanding method based on the massless Dirac fermion (MDF) approximation for the low-energy excitations of electrons in the π bands. The response of the sapphire layer is described by a dielectric function consisting of several Lorentzian terms. We evaluate the total electrostatic potential in the plane of the upper graphene sheet for a particle moving at the sub-threshold speed for the wake effect in a single, free graphene. We show that, when the space between graphene sheets is air, there is only a sharp, somewhat asymmetric peak in the potential at the position of the particle. On the other hand, when the space is filled with sapphire, there is a prominent wake pattern in the potential behind the particle resulting from a low-frequency plasmon-phonon mode. It can be noted that the analytical MDF model reproduces the overall shape and the period of quasi-oscillations in the wake potential obtained from the ab initio calculations.
