Hello Matt,
No for Ge nothing works. I am getting negative bandgap while using OT.
Seems that there is LUMO occupied with lower energy than HOMO (see below).
The output below is for OT with cut-off radius 2A. Everything works fine
for Silicon system as it not metallic in DFT but not for Ge.
Regards,
Anurag
