Abstract The electron temperature T e dependent electron density of states g ( e ) , Fermi–Dirac distribution f ( e ) , and electron–phonon spectral function α 2 F ( Ω ) are computed as prerequisites before achieving effective electron–phonon coupling factor G e – ph . The obtained G e – ph is implemented into a molecular dynamics (MD) and two-temperature model (TTM) coupled simulation of femtosecond laser heating. By monitoring temperature evolutions of electron and lattice subsystems, the…
