  • Abstract
    Today´s coated conductor techniques are aimed to minimize by grain alignment the grain boundary problem of high-Tc superconductors. We present a new approach to enhance the critical current density of coated conductors, which is based on a modified microstructure of the substrate, to utilize grains with large aspect ratios. Calculations clearly show that by using such substrates critical current densities close to the intragrain Jc are possible.
