Hey,
I'm running a semi-quantitative simulation and I have a surface charge densitiy of 10 electrons per square nanometer. Is this anything realistic? The surface is immersed in an electrolyte so the total charge is cancelled by ions from the solution. But still, can I pack 10 e's on such a surface?

I know there are proteins with 10 formal charges which are on the same scale (of course also surrounded by counter ions).

Thanks for any feedback.

This would correspond to ~14GV/m (WolframAlpha query) - looks unrealistic.
