Two-temperature model (TTM) parameters (G, Ce, K) calculated with XTANT-3

Two-temperature model parameters

Electron-temperature dependent parameters for modeling of laser-irradiated materials: electron-phonon coupling (G), electron heat capacity (Ce), and electron heat conductivity (Ke)

Up-tp-date version is available at: https://github.com/N-Medvedev/XTANT-3_coupling_data

The electron-ion (electron-phonon) coupling parameter, electronic heat capacity, and electronic heat conductivity at high electronic temperatures (Te) were calculated with the help of the nonperturbative dynamical coupling formalism and Kubo-Greenwood method. The method was implemented in the XTANT-3 code (https://github.com/N-Medvedev/XTANT-3). When using this dataset, please, cite the corresponding papers.

Note: the dataset is for high electronic temperatures whereas the room-temperature values may not always be reliable
