Dear QE users....<br><br>I have some doubts, not exactly related to QE but i need to solve these problems to continue using the QE to finish my calculations on adsorption of some molecules in MgO surface......<br><br>I want to simulate an MgO surface (slab) with 7x7 atoms in XxY axes and 6 atoms in Z axis.... I need the positions of the atoms to have my input file, than i can make a "relax" calculation os this surface...<br>
<br>I tryed to get the MgO.cif file and make a supercell from it, but i had no success...<br clear="all"><br>If you can help me with this i really appreciate....<br><br>And i need to know the multiplicity of this surface, how could i know it?<br>
<br>Sorry because i have basic questions, and thank you a lot....<br><br>-----------------------------------------------------<br>Thiago Guerra<br>Mestrando - Programa de Pós Graduação em Engenharia de Defesa<br>Instituto Militar de Engenharia (IME) <br>
