Phonon dispersion spectra for the relaxed FE-I (a) and FE-II (b). Evolution of the total free energies of Co2Cl2 monolayer at 300 K calculated by first-principles molecular dynamics for the FE-I (c) and FE-II (d). Spin-polarized electronic band structures and orbital-projected partial density of states (PDOS) for FE-I phase (e) and FE-II phase (f) of Co2Cl2 monolayer. Black and red curves denote the spin-up and spin-down bands, respectively. The Fermi level is set to zero.
