Dear all,
I wanted to built a supercell for my system in QE. I went through the forum and
saw some procedures. I followed this:
1. Upload the unit cell in XcrySDen, display the asymmetric unit, modify the
number of unit drawn to fit the shape of the desired supercell (2*2*2) and then
save the XSF file.
2. From the XSF file, the coordinates of atoms in the supercell are obtained,
in angstrom.
But the problem is with the CELL. How should I built the CELL parameters and
read the final structure with XCrySDen?
Note: I choosed the same ibrav as for the unit cell, then multiply the celldm
by 2, but the structure does'nt look fine in XCrySDen.
Thans for your help
