Title: La 2-xSr xCuO 4 superconductor nanowire devices

La 2-xSr xCuO₄ nanowire devices have been fabricated and characterized using electrical transport measurements. In addition, nanowires with widths down to 80 nm are patterned using high-resolution electron beam lithography. However, the narrowest nanowires show incomplete superconducting transitions with some residual resistance at T = 4 K. Here, we report on refinement of the fabrication process to achieve narrower nanowire devices with complete superconducting transitions, opening the path to the study of novel physics arising from dimension-limited superconductivity on the nanoscale.
