Nur Mohammed Send me your email and I will send you a video of how to calculate a bandgap

Ilham Ben Amor The whole point of ResearchGate is to share knowledge so that all benefit. Private emails are not good in this regard as they help only one person at best and if they are inaccurate or inadequate then they can be misleading without correction from other experts. Sharing of knowledge is power not knowledge is power...
