Dear QE users<br><br><br><br>1-I want to simulate the charged oxide semiconductor slab, with desired surface charge. if choosing different values for the "tot_charge=...." is enough, for do this?<br>or there is more consideration.............<br>
<br>I think if we introduce excess charges by "tot_charge" utility in slab , after scf they should be localize on the surface, as the "surface charge" is this true?<br><br>Thanks in advance.<br><br><br>
