For the case of Al2O3 (0001), since the gamma angle is 120°, you want build a cell with u’=u and v’=u+2v, where u and v are the original surface lattice vectors and u’ and v’ the ones for the rectangular cell.<br> <br> You can for example do this in VESTA, Edit->Edit Data->Unit Cell. First remove the symmetry to get a P1 structure and the with the “Option" button redefine you lattice as ((1 1 0), (0 2 0), (0 0 1)).<br> <br> Hope that helps.<br> <br> Best regards,<br> -uli<br> --------------------------------------------------------------<br> SNF Prof. Dr. Ulrich Aschauer<br> Universität Bern<br> Departement für Chemie und Biochemie<br> Freiestrasse 3<br> CH-3012 Bern<br> Tel. <span>+41 (0)31 631 5629</span><br> <a href="mailto:ulrich.aschauer@dcb.unibe.ch" target="_blank">ulrich.aschauer@dcb.unibe.ch</a><br> <a href="http://www.dcb.unibe.ch/" target="_blank">www.dcb.unibe.ch</a><br> Büro: N431<br> --------------------------------------------------------------<br> <br><blockquote type="cite">On 04 Jul 2016, at 11:54, Andrey Chibisov <<a href="mailto:andreichibisov@yandex.ru" target="_blank">andreichibisov@yandex.ru</a>> wrote:<br> <br> How to build the rectangular surface of Al2O3(0001)?<br> Than, the angle between a and b parameters is 90 degrees.<br> <br> --<br> Best regards,<br> Andrey Chibisov.
