✦ Synopsis

Abstrnet. This paper describes an investigation of the microscopic configuration of the "barrier" which exists at the boundary in high Tc grain boundary junctions. A model for describing the properties of bicrystal and biepitaxial grain boundary junctions is proposed. Two channels for transport currents are assumed, the supercurrent being carrier by one channel only. The measurable macroscopic parameters of a junction, (critical current density and normal state resistance) are computed in terms of the microscopic parameters that appear in this model. The model well describes major features of the characteristics observed for high Tc bicrystal junctions.
