摘要: We study the superconducting properties of a doped one-layer graphene by using model in which interparticle attraction is caused boson (phonon-like) excitations. dependence gap Δ and mean-field critical temperature TcMF on carrier density, strength, characteristic (Debye) bosonic frequency. In addition, we temperature-carrier density phase diagram taking into account thermal fluctuations order parameter. show that result significant suppression TcMF, such real (Berezinskii-Kosterlitz-Thouless) Tc much lower than TcMF.
