To evaluate and take advantage of the properties of functionalized graphene , it is important to understand how its electrical attributes ( such as carrier scattering , carrier concentration , charge polarity , quantum - capacitance enhanced doping , energy levels , transport mechanisms , and orbital hybridization of energy - bands ) are influenced by a change in carbon ' s structural conformation , hybridization state , chemical potential , local energy levels , and dopant / interface coupling induced via functionalization or molecular interactions .
