Impurity induced broadening of Drude peak in strained graphene
V. O. Shubnyi, S. G. Sharapov, Y. V. Skrypnyk
The recent experimental study of the far-infrared transmission spectroscopy of monolayer graphene has shown that the Drude peak width increases by more than per of app…
Coherent spectrum rearrangement in graphene: an additional nodal point and an impurity band appearance
Yuriy V. Skrypnyk, Vadim M. Loktev
It is demonstrated that a new nodal point is forming and a domain with anomalous dispersion is unfolding in the spectrum of charge carriers in graphene, when the concentration of w…
Metal-insulator transition in hydrogenated graphene as manifestation of quasiparticle spectrum rearrangement of anomalous type
Yuriy V. Skrypnyk, Vadim M. Loktev
We demonstrate that the spectrum rearrangement can be considered as a precursor of the metal-insulator transition observed in graphene dosed with hydrogen atoms. The Anderson-type…
Electrical conductivity in graphene with point defects
Yuriy V. Skrypnyk, Vadim M. Loktev
The electrical conductivity of graphene containing point defects is studied within the binary alloy model in its dependence on the Fermi level position at the zero temperature. It…
Numerical simulation evidence of spectrum rearrangement in impure graphene
S. S. Pershoguba, Yu. V. Skrypnyk, V. M. Loktev
By means of numerical simulation we confirm that in graphene with point defects a quasigap opens in the vicinity of the resonance state with increasing impurity concentration. We p…
Local density of states subject to finite impurity concentration in graphene
Yuriy V. Skrypnyk, Vadim M. Loktev
It is demonstrated that there is a characteristic impurity concentration, at which variation with concentration and overall appearance of the local density of states at the impurit…
