  • TITLE: A Detailed Study of the Role of Fermi Energy in Determining Properties of Superconducting NbN

    AUTHORS: G. P. Malik

    KEYWORDS: EF-Incorporated Equations for Tc, Δ0, and j0of a Superconductor, NbN

    JOURNAL NAME: Journal of Modern Physics, Vol.8 No.1, January 23, 2017

    ABSTRACT: The recent concern with the role of Fermi energy (EF) as a determinant of the properties of a superconductor (SC) led us to present new EF-dependent equations for the effective mass (m*) of superconducting electrons, their critical velocity, number density, and critical current density, and also the results of the calculations of these parameters for six SCs the Tcs of which vary between 3.72 and 110 K. While this work was based on, besides an idea due to Pines, equations for Tc and the gap at T = 0 that are explicitly EF-dependent, it employed an equation for the dimensionless construct that depends on EF only implicitly; k in this equation is the Boltzmann constant, θ is the Debye temperature, and P0 is the critical momentum of Cooper pairs. To meet the demand of consistency, we give here derivation of an equation for y that is also explicitly EF-dependent. The resulting framework is employed to (a) review the previous results for the six SCs noted above and (b) carry out a study of NbN which is the simplest composite SC that can shed further light on our approach. The study of NbN is woven around the primary data of Semenov et al. For the additional required inputs, we appeal to the empirical data of Roedhammer et al. and of Antonova et al.
