Dear Wien users,
When I calculate a superlattice of ZnTe/CdTe, the spacegroup is Pmm2.
But The program found a d state of Te atoms(There are a partial state of d in *.output2 file
and it is a ghost band.) The energy level is located at -0.25Ry. How can I understand it. You know
the Te 4d state is very deep!
Best Wish to You!
