Real part of dielectric constants in case of graphene nanoribbons?

09 September 2018 1 3K Report

I need to calculate real part of dielectric constant in case of graphene nanorribbons. Please suggest how we can calculate , we need this since no band gap is there in case of graphene, but it is there in case of GNRs.

Thanks dear, but i want to calculate in ZGNR and which is pure quantum mechanical problem, your told answer seems me classical right?
