Abstract

We report the shock-wave synthesis at a yield ≳80% by volume of the single copper layer thallium superconductor of composition Tl2Ba 2CuO6. The as-synthesized material displays zero resistance near 55 K and a diamagnetic onset to bulk superconductivity at 70 K. Lattice imaging indicates that the superconducting microcrystals consist of a novel defect microstructure involving an intergrowth of two copper-oxygen layers probably interleaved by partial thallium and barium occupancy.
