Ab initio molecular dynamics (AIMD) simulations of the BMP-TFSI monolayer structure on graphite were performed to identify changes in the work function due to a temperature induced movement of the ions. In these simulations, we employed a canonical (NVT-) ensemble with a Langevin thermostat at a temperature of 298 K and time steps of 1 fs. In order to allow a better reorganization of the adsorbed ions the unit cell was doubled along the lattice vector a, the total run time of the AIMD simulation was 16.4 ps.
