1 | Mattis, Daniel C. | Ratio 2Δ0/kTc in superconductivity | In high-temperature superconductors, values of the ratio R-2Δ0/kTc have been reported in the range 2-10, whereas low-temperature superconductors rarely deviate by as much as 50% from the BCS prediction R =3.54. Could this variability relate to the density of states near the Fermi surface? Our calcu... | Density of state; Superconductors | 1991-12 |
