<div>Dear Wien2k community (and specially Prof. Marks),<br>
<br>
</div>
Is there any situation where the "old" "mini" may present a better performance than "MSR1a" or this is an almost impossible situation ?<br>
</div>
I am working with III-V semiconductors and their heterostructures. Sometimes I am trying to optimize the heterostructure fixing the atomic positions in the "thick" layer using the correspondent optimized bulk values. If I remember correctly, Prof. Marks
has criticized this procedure. Would this significantly affect the heterostructure optimization ?
<br>

All the best,<br>
