Toward a theory of superconductivity in twodimensional systems with arbitrary carrier densities in an external magnetic field
Abstract
The authors derive selfconsistent equations that describe the behavior of the superconducting gap (order parameter) and chemical potential of metallic twodimensional (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.
