AB  - We study the effects of variation in the doping density of graphene on hybridization taking place between its Dirac plasmon and the surface optical phonon modes in a SiO2 substrate, and show that this hybridization may be probed by a point charge that moves over graphene at a speed comparable to graphene’s Fermi speed. Using the dielectric-response formalism within the random phase approximation, we show that the plasmon-phonon hybridization exerts strong effects on the wake pattern in the induced potential in the plane of graphene, as well as on the stopping and image forces on the incident charge, in a manner that may be controlled by changing the doping density of graphene.

AB  - The influence of deposition and post-deposition annealing parameters on the structure and optical properties of TiO2 thin films synthesized by reactive e-beam evaporation is reported. Pure Ti (99.9%) was evaporated in oxygen atmosphere to form thin films on Si (100) and glass substrates. Depositions were conducted on substrates held at room temperature and at 200-400 degrees C heated substrates. Post-deposition annealing was done for 3 h at 500 degrees C in air. Compositional and structural studies were performed by Rutherford backscattering spectrometry, X-ray diffraction, and X-ray photoelectron spectroscopy, and optical properties were studied by ultraviolet-visible spectroscopy and analytically by pointwise unconstrained minimization approach method. It was found that both the structure and optical properties of the films are strongly influenced by the deposition and processing parameters. All deposited samples showed good stoichiometry of Ti:O similar to 1:2. Depending on the substrate temperature and oxygen pressure in the chamber during the deposition, anatase-rutile mixed films were obtained, and in some cases TiO and Ti2O3 phases were observed. Substrate deposition temperature appears to play the major role on the final structure of the films, while post-deposition annealing adds up for the lack of oxygen in some cases and invokes crystal grain growth of already initiated phases. The results can be interesting towards the development of TiO2 thin films with defined structure and optical properties. (C) 2015 Elsevier B.V. All rights reserved.

AB  - We study correlated motion of two ions resulting from a dissociative grazing scattering of a slow diatomic molecular ion on supported graphene. A low-frequency collective mode resulting from hybridization of graphenes Dirac plasmon and the optical phonon modes in the insulating substrate may be excited by matching its phase velocity with the ion speed lower than the graphene Fermi speed. The resulting wake effect gives rise to the strongly directional, oscillatory patterns in both the inter-particle interaction potential and the total stopping power for the two ions, which may be detectable in their angular and the energy loss spectra.

AB  - The influence of sputtering parameters and annealing on the structure and optical properties of TiO2 thin films deposited by RF magnetron sputtering is reported. A pure TiO2 target was used to deposit the films on Si(100) and glass substrates, and Ar/O-2 gas mixture was used for sputtering. It was found that both the structure and the optical properties of the films depend on deposition parameters and annealing. In all cases the as deposited films were oxygen deficient, which could be compensated by post deposition annealing. Changes in the Ar/O-2 mass flow rate affected the films from an amorphous like structure for samples deposited without oxygen to a structure where nano crystalline Futile phase is detected in those deposited with O-2. Annealing of the samples yielded growth of both, ruffle and anatase phases, the ratio depending on the added oxygen content. Increasing mass flow rate of O-2 and annealing are responsible for lowering of the energy band gap values and the increase in refractive index of the films. The results can be interesting towards the development of TiO2 thin films with defined structure and properties. (C) 2015 Elsevier EN. All rights reserved.

AB  - We use the dielectric response formalism to show how an incident charged particle may be used to probe the hybridization taking place between the Dirac plasmon in graphene and the surface optical phonon modes in a SiO2 substrate. Strong effects of this hybridization are found in the wake pattern in the induced potential, as well as in the stopping and image forces that act on the incident charge in a broad range of its velocities. Particularly intriguing is the possibility to control the plasmon-phonon hybridization by varying the doping density of graphene, where the regime of a nominally neutral graphene is expected to give rise to dramatic effects in the energy loss of charged particles that move at the velocities below the Fermi velocity of graphene.

AB  - The inter-particle interaction energy and the total stopping power for a correlated motion of two point charges that move above supported graphene at a speed smaller than the graphene Fermi speed are theoretically investigated. The slowly moving charges excite lowfrequency collective mode which survives the Landau damping in the region of the intraband single particle excitations in doped graphene. We show that this mode gives rise to wake effect manifested in the oscillatory patterns in both the interaction energy and the stopping power when the charges move with their inter-particle axis pointing in the direction of motion.
