WebWe demonstrate that electron–phonon scattering in the Cu–Se layer dominates at low T(< 500 K), while contributions from the Bi–O layer become increasingly significant at higher T. At room temperature, ZTis calculated to be 0.48 and can be improved by 30% through weakening PO phonon scattering in the Cu–Se layer. WebPhonon–phonon scattering selection rules and control: an application to nanofriction and thermal transport† Antonio Cammarata * Phonon–phonon scattering processes are the crucial phenomena which account for phonon decay, thermal expansion, heat transfer, protein dynamics, spin relaxation and related quantities.

Web11 de out. de 2024 · Due to the phonon boundary inelastic scattering and other phonon transport mechanism, the thermal transport across the ultrathin HfO 2 film below 20 nm may manifest remarkable thickness and temperature dependences for the in-operation HfO 2 film–based nanoscale devices. However, it is still not clear what influence on the thermal … WebHá 1 dia · We identify topologically nontrivial Dirac surface states and multiple van Hove singularities (VHSs) in the vicinity of the Fermi level, with one VHS near the K point exhibiting nesting wave vectors in proximity to the x 30 CDW wave vector.

Web1 de jan. de 2024 · High-temperature phase tin selenide (β-SnSe) possesses a large power factor owing to its innately complex band structure.A detailed analysis of the electron-phonon (e-ph) intervalley scattering between the different non-parabolic valleys in β-SnSe remains to be disclosed.Using ab initio approach, the phonon-limited carrier mobility, … WebThese considerations allow us to estimate the effect of boundary scattering in a solid solution at T ^- BD, since point-imperfection scattering should be very stronf in such a material. Suppose that the phonon-phonon scattering is mainly due to umklapp processes with Tu =1/Bw2. Then, assuming as an approximation that only one scattering process ... Web2 de jul. de 2013 · Abstract.
