General Questions and Answers / Bandstructure of graphene

« on: April 17, 2020, 19:38 »

After doping of graphene i calculate the bandstructure and the bangap opens at dirac point but the valence band  crosses fermi level but donot overlap conduction. How classify this material as semiconductor or semimetal or dengerate semiconductor or metal. i attach that Bandstructure

One thing more I am learning this  software and can anybody tell how get theoritical aspect DFT LCAO and NEGF theory like  some good books or research papers
