Title: Toward a theory of superconductivity in two-dimensional systems with arbitrary carrier densities in an external magnetic field

Abstract

The authors derive self-consistent equations that describe the behavior of the superconducting gap (order parameter) and chemical potential of metallic two-dimensional (2D) systems as a function of external magnetic field H, temperature T, and carrier density. For systems with low carrier densities, the pairs are localized below T{sub c}; the authors show that in such systems the derivative dH{sub c2}(T)/dT at the point T=T{sub c} is considerably smaller than it is for a system in which Cooper pairs form. They find that in external fields that satisfy the criterion for the quantum limit, these systems are characterized by the appearance of a nontrivial nonuniform order parameter at sufficiently high temperatures. 32 refs., 2 figs.
