摘要
The results of a computer simulation of the atomic structure of interfaces in YBa(2)Cu(3)0(7-delta) (twin boundary and large-angle symmetrical tilt grain boundary) are presented, These results allow us to determine the lattice displacements and distortions in the vicinity of analyzed interfaces. Basing on the strain level approximate to 0.01 as a phenomenological criterion for the suppression of superconductivity, estimates of the thickness of the nonsuperconducting regions enveloping interfaces are made.
