Theoretical investigation onthe effect of carrier imbalance on conductivity of Double Layer Graphene System (DLGS) in presence of long range and short range scatterershas been done at T = 0 K within the framework of Boltzmann Transport equation. Wedescribed here with some variableparameters like carrier imbalancenr, ratio of dielectric constant εr, and distance dbetween two monolayers. The influence of the scattering mechanisms specifically Short range scattering and Coulomb chargeimpurity scattering have been assessed. It is found thatthe short range scatterers play vital role to affect the conductivity. Maximum conductivity has been attained in the absence of point defect. Influence of the screening effect between two monolayeris observed as interlayer distance d~20 nm. Further, italso noticed that as the value of relative carrier concentration nr increases, the peak is shifting towards higher value of εr. [ABSTRACT FROM AUTHOR] |
