Dear all, I'm trying to simulate the interface between a charged doped graphene layer and a liquid electrolyte. I would like to treat the solvent explicitly. So I should place some molecules of the solvent in the vacuum region of my slab model. I've seen that with the OpenMX code it is possible to use the ESM method and define a potential to confine the liquid in a certain portion of the space between periodic images of the substrate. This prevents the liquid filling all the vacuum space of the supercell during MD.
Here is an explicative figure: http://www.openmx-square.org/openmx_man3.7/node118.html Is something similar implemented in Quantum Espresso? Or is it possible to obtain it using constraints on the coordinates? Thanks a lot in advance and best regards, Mauro Sgroi. Centro Ricerche FIAT.
