The purpose of this work is to elaborate the functional integral method in quantum field theory Dirac fermions fermion gas a graphene single layer at vanishing absolute temperature. starting point be assumed as fundamental principle explicit expression action system. efficient mathematical tool used study generating containing Grassmann parameters anticommuting with operators.
In the present work we apply functional integral method to study of quantum field theory collective excitations spinless Dirac fermion in graphene at vanishing absolute temperature and Fermi level . After introducing Hermitian scalar describing these establish expression containing a series The explicit expressions several terms this were derived. Then consider second order approximation denote corresponding approximate We shall demonstrate that can be devided into two parts: background...
In this study, the thin films of graphene (Gr) doped with copper (I) chloride (CuCl) were fabricated on a (Cu) substrate by chemical vapour deposition method at 1000oC in mixture gases (Ar, H2, and CH4) combined annealing 220oC to vapourise CuCl powder. The morphology, structure, electrical, electrochemical characteristics CuCl-doped Gr (CuCl-Gr) investigated via field emission scanning electron microscopy (FESEM), Raman spectroscopy, four-probe cyclic voltammetry. results spectroscopy...
