From: Measurement of Electron-Ion Relaxation in Warm Dense Copper
Electron – ion couplings of warm dense copper.
(a) The G obtained by Eq. (1) at 2, 4 and 6 ps for three different energy densities are displayed at the corresponding electron temperatures together with electron-phonon coupling calculations using Eq. (2) with both liquid DOS and ambient solid DOS21. For comparison, the electron-phonon coupling constant of solid Cu is also shown28.
