These files are the final positions resulting from density functional theory calculations of methylbenzenes on graphene. the defaults for parameters controlling damping function ( VDW_S6, VDW_SR, VDW_D ) are available only for the PBE functional. The calculation of the phonon dispersion curves is performed within the direct supercell method via. To obtain single water binding reference curves, we performed DFT calculations using Quantum ESPRESSO 28 by employing two different non-local correlation functionals of vdW-DF2 9 and vdW-DF2 c09x 20. This page lists application software available. The norm-conserving, designed nonlocal pseudopotentials were generated with the OPIUM package [35,36]. All calculations employed a 140 Ry planewave cutoff and 1×1×1 and 8×8×8 k-point meshes for the isolated HgCl 2 molecule/dimer and the periodic solids, respectively. > It seems a problem related with vdw forces. new r_m : 0. 7 SGI, Alpha Parallelism22 3.
