La2−xSrxCuO4 superconductor nanowire devices
چکیده انگلیسی


• We grew La2−xSrxCuO4 (LSCO) films using ALL-MBE.
• LSCO films were characterized by Atomic Force Microscopy and mutual inductance measurements post-growth.
• Single nanowire LSCO devices were fabricated using high-resolution electron beam lithography.
• Electrical transport measurements were used to characterize LSCO nanowire properties.

La2−xSrxCuO4 nanowire devices have been fabricated and characterized using electrical transport measurements. 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 the 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.
