<!-- Thanks for providing feedback! Please provide the information below. --> ## File in which the problem appears 12 band structures ## Problematic sentence The band structure has two band gaps: direct, the band gap at k=0, E'_G ... ## Correct version I suspect E'_G has to do with the direct band gap, but it quite hard to derive as it is written. The first few times I read it, 'E'_G and indirect gap E_G' became the main thing I read, which does not seem to be intended.
