Si bandgap according to the workshop (handsonII) comes as 0.6 ev. This is far from 1.12 ev. Does it need to incorporate anything more to get a good agreement?

Dear Kuntalroy,
if you want to get correct electronic band structure, you have to use HSE functional.You can read [ PRL B 80,115205(2009)] for further detail
