<div>Dear users and developers</div><div>I wish to ask if this command<br></div><div></div><div><br></div><div>SURFACE_DIPOLE_CORRECTION T<br>SURF_DIP_DIR Z <br></div><div><br></div><div>Is this a universal MUST whenever we model ANY surface</div><div>under PERIODIC XYZ?</div><div>(I assume, this is not important under PERIODIC XY.)<br></div><div></div><div></div><div><br></div><div>May I state that<br></div><div>this is important for a metal surface (electronic delocalizations)<br></div><div>where an adsorbed molecule (on the top)</div><div>is symmetric in respect to X and Y <br></div><div>but not in respect to Z: like, OH anion under the vertical orientation?</div><div><br></div><div>How important
</div><div><div></div><div>SURFACE_DIPOLE_CORRECTION T</div><div>should be if one would model systems like</div><div>2-3 layered graphite, <br></div><div>where the layers are well separated and barely "feel" each other (see attached),<br></div><div>or</div><div>2 layer silica with a disordered water cluster at the top,</div><div>hence, there is no obvious symmetry and, due to the nature of atoms, <br></div><div>charges are rather localized (see attached).</div><div><br></div><div>This is about, how universal is this article</div><div>
