thanks Dr. Vitaly V. Chaban for your reply. i already simulated the CNT without doping and i have developed a structure with the doped CNT.
now if i add the dopant atoms in my forcefield file (for example, in my case i add nonbonded parameters to my ffnonbond.itp and bonded parameters to my bonded.itp and so on) will it be the correct way to do the simulation? and it would be very nice if you could explain the statement, "You must account for the effect of your new fragments on electron density of the entire nanostructure." a little bit further. thanks for your time On Mon, Jun 30, 2014 at 4:01 PM, Dr. Vitaly Chaban <vvcha...@gmail.com> wrote: > Simulation of doped nanostructures is much more complicated than > described below.
