  I have been running PGB band solver for a structure and what it gives at output is only one band gap but if I look PGB solver again then I think there should be one more band gap between 0.4 and 0.2 but the PGB solver isn’t showing it. So anyone can tell what I’m doing wrong or why it isn’t showing that band gap region.
