Data from Ferdowsi University Advance Knowledge in Condensed Matter (The role of electron-phonon interaction on the transport properties of graphene based nano-devices)

By a News Reporter-Staff News Editor at Physics Week -- Data detailed on Condensed Matter have been presented. According to news originating from Mashhad, Iran, by VerticalNews correspondents, research stated, "Transport through a nano-device in the presence of electron-phonon interaction has been studied by using unitary-transformation scheme together with the non-equilibrium Green's function formalism. The non-interacting Hamiltonian is written within the tight binding model and left/right electrodes are described in wide-band approximation."

Our news journalists obtained a quote from the research from Ferdowsi University, "The interaction between electrons is studied in the mean-held Hubbard model. Our results indicate that both phonon-restricted and phonon-assisted transport through two different configurations of graphene quantum dot occur."

According to the news editors, the research concluded: "Also, the electron-phonon interaction screens the electron-electron interaction, and reduces the spin polarization."
