Beschreibung
Zusammenfassung:We consider the interplay between superconducting coupling and dopant impurity 
 
 scattering of charge carriers in planar square lattice systems and examine the physical 
 
 conditions (doping level, temperature, local symmetry of coupling and scattering 
 
 potentials) necessary in this model system to obtain a d-wave superconducting order, like 
 
 that observed in real doped cuprate HTSC materials. Using the Lifshitz model for the 
 
 disorder introduced into system by dopants, we analyze also the nonuniform structure of 
 
 such a d-wave parameter, including both its magnitude and phase variation. The results 
 
 indicate that d-wave superconductivity becomes possible in a doped metal until it is 
 
 destroyed at too high doping levels.
