<div>Dear Lorenzo,<br>
</div>
you cannot specify different periodicity, you have to build a
super-cell, as big as the 3x3 cell of the first material, or the
2x2 cell of the second, then you fill it with 9 units of the
first material and 4 of the other. This can be done by hand (the
first time it'll take you an hour or two), or there are some
softwares that can help you I have never used one, as hence I
cannot recommend any.<br>
