I want to simulate a single layer of graphene that interacts with external non-uniform electric field.For example, by locating two planes of opposite charged particles each side of layer or using e-field command. The pair interaction between C atoms which I have to use is airebo, and it works well when there is no external field.
However, I do not know how to define the interaction between charged particles and C atoms. I got an error when I apply the electric field which means I missed something.
does anyone have the experience of simulating single layer of graphene with external e-field?
Thank you in advance,
