Contribution of inter- and intraband transitions into electron–phonon coupling in metals

نویسندگان

چکیده

We recently developed an approach for calculation of the electron-phonon (electron-ion in a more general case) coupling materials based on tight-binding molecular dynamics simulations. In present work we utilize this to study partial contributions inter- and intraband electron scattering events into total Al, Au, Cu elemental metals AlCu alloy. demonstrate that interband plays important role electron-ion energy exchange process Al AlCu, whereas $d-d$ transitions are dominant Au Cu. Moreover, exhibit qualitatively different dependencies temperature. Our findings should be taken account interpretation experimental results parameter.
