Abstract
At the present time, the properties of high angle grain boundaries det ermine the macroscopic electromagnetic character of all polycrystallin e high T-c superconducting cuprates and dictate the types of applicati ons for which these materials can be developed. Understanding and cont rol of their grain boundary properties thus continues to be a key rese arch issue. As was emphasized by Prof. Robert W. Balluffi in his work on internal interfaces, a complete understanding of grain boundary pro perties requires systematic study of single grain boundaries for which the structure, crystallography, and properties are investigated in a coupled manner. It is precisely these kinds of experiments that have y ielded the most insight into the general properties, the range of prop erties, and structure-property relationships for grain boundaries in t he high T-c superconductors. This paper describes the bicrystal studie s that have been conducted by our groups at the University of Wisconsi n and their key results.
