Hi everybody

I'm trying to find band gap by 'GW' i found 2.6 but experimentally 2.3, please can you help me how i can change input file till result become close to real band gap ..I'm using abinit 7


with regards ...

Dear Bewar

1: You can do convergence study for your results.

2: May be results of bethe_salpeter calculation closer to the experimental data, and GW need to be corrected.
