Temperature–carrier-concentration phase diagram of a two-dimensional doped d-wave superconductor
The finite-temperature properties of a two-dimensional d-wave superconductor with the Lifshitz disorder, introduced by dopants, are studied. The doping dependence of the mean-field critical temperature Tc MF and of the superconducting critical temperature Tc defined by the Berezinskii—Kosterlitz...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Zusammenfassung: | The finite-temperature properties of a two-dimensional d-wave superconductor with the
Lifshitz disorder, introduced by dopants, are studied. The doping dependence of the mean-field
critical temperature Tc
MF and of the superconducting critical temperature Tc defined by the
Berezinskii—Kosterlitz—Thouless transition are calculated at different values of coupling, dopant
potential, and intermediate boson energy. It is shown that superconductivity tends to disappear
with increasing doping when the dopant potential is large enough, though the metallic properties
of the system are preserved. |
