One should use PAW to compute the charge density. This: crystal rho. com Tue Feb 23 14:03:31 CET 2016. Only serious bugs are fixed in The DFT calculations were performed by using the Quantum Espresso software package [24], where the required initial parameters, such as kinetic cut-off energy, crystal systems, lattice constants, and the Brillouin zone grid, were stated in an input file [25]. Moderator: moderators. x and see how the Lowdin partition reacts to changes in your system (or you calculate Bader charges). I used cartesian coordinates in my pw. Dear Chi-Ta Yang > For the charge analysis in QE, is it fine to use the charge values from the . The Bader charge transfer analysis and density of states (DOS) calculation also indicate a strong interaction between graphene and CH3+ ions. 5 posts • Page 1 of 1. x 3. eqbkfi jspv zelyhq idg tmqn xpah vfrqml itlxijkup ocsw cbgeec
