However, we find that its in-plane static screening remains relatively isotropic for momenta relevant to elastic long-range scattering processes. On the other hand, the collective electronic excitations in the system exhibit a strong anisotropy. Band nonparabolicity, due to interband couplings, leads to a plasmon frequency which scales as nß, where n is the carrier concentration, and ß<12. Screening and charge distribution in the out-of-plane direction are also studied using a nonlinear Thomas-Fermi model. 000048126 536__ $$9info:eu-repo/grantAgreement/ES/MINECO/FIS2011-23713$$9info:eu-repo/grantAgreement/EC/FP7/604391/EU/Graphene-Based Revolutions in ICT And Beyond/GRAPHENE 000048126 540__ $$9info:eu-repo/semantics/openAccess$$aby-nc-nd$$uhttp://creativecommons.org/licenses/by-nc-nd/3.0/es/ 000048126 590__ $$a7.512$$b2014 000048126 591__ $$aPHYSICS, MULTIDISCIPLINARY$$b6 / 78 = 0.077$$c2014$$dQ1$$eT1 000048126 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/publishedVersion 000048126 700__ $$aRoldán, R. 000048126 700__ $$aWang, H. 000048126 700__ $$aXia, F. 000048126 700__ $$aAvouris, P. 000048126 700__ $$0(orcid)0000-0001-9273-8165$$aMoreno, L.M.$$uUniversidad de Zaragoza 000048126 700__ $$aGuinea, F. 000048126 7102_ $$12003$$2395$$aUniversidad de Zaragoza$$bDpto.
