Abstract

A model, based on universal properties of high-

T_{c}

superconductors only, is presented for the transport characteristics of grain boundaries in these materials. The model accounts for the superconducting as well as for the normal-state transport properties observed in a comprehensive study of

{YBa}_{2} {Cu}_{3} O_{7−δ}

[001]-tilt bicrystalline grain boundaries with varying misorientation angles and of two different symmetries.
