文摘

Real and imaginary parts of optical conductance separately are calculated. Absorption coefficient in monolayer circular graphene quantum dots is calculated. Absorption coefficient in bilayer circular graphene quantum dots is calculated. Comparing between Absorption coefficient of mono and bilayer circular graphene quantum dots was done. Effect of external magnetic and electric filed on absorption coefficient is investigated.
