We consider a two-dimensional model appropriate for cuprate compounds and recently discovered superconductor magnesium-diboride (MgB2) which also reveals layered structure. By using the McMillan approximation we present the result of calculations of critical temperature Tc. It is shown that the critical temperature is enhanced due to the influence of anisotropy and nonadiabaticity.EnglishElectron-phonon interactionsLayered systemsMigdal theoremNonadiabatic superconductorsAnisotropyApproximation theoryFermi levelMagnesium compoundsPhononsLayered systemsSuperconducting materialsEffects of anisotropy on the critical temperature in layered nonadiabatic superconductorsArticle10.1016/S0921-4534(02)01995-0
