Explore a 33-minute physics lecture examining the band structure transformation of the avoided crossing type in impure graphene, presented at the XXIX DAVYDOV READINGS conference commemorating 50 years of the Davydov's soliton. Delve into theoretical physics research from the Bogolyubov Institute for Theoretical Physics, investigating how impurities affect graphene's electronic band structure and the phenomenon of avoided crossing in this advanced materials science presentation.
