Dear Izaak You (often) suppose to investigate an "isolated" dopant or defect, but in fact you are always simulating an array (a superlattice) of impurities in a semiconductor (SiC) host. In principle you should verify that your results are reasonably insensitive to the supercell volume. In

2011-06-09 Thread Sanda Botis
Hi, Why not do a complete relaxation (no atoms fixed) and compare it with a partial relaxation (allow to relax only several atoms around your defect). Assuming that you have some experimental data to compare with, you will find out which calculation is better suited for describing a particular typ
