In a hypothetical, electrically neutral, ideal crystal, where all unit cells are identical, even the ones at the surface:
What would the average value of the electrostatic potential be compared to that of the vacuum outside the crystal?
Would it be the same or more positive?
As a simple example one could consider a cubic lattice where each unit cell contains a localized positive and a smeared out negative charge.
