Direct-Write Nano Josephson Superconducting Tunnel Junctions

Abstract

This report is for the period May 15, 2015 to February 15, 2021, and contains a summary of our key results, and accomplishments. The specific aim of this grant was to study the basic device physics of helium ion fabricated Josephson junctions and how their transport properties are affected by anisotropy in high-temperature superconductor materials. Our work involved materials synthesis, nanoscale device fabrication and advanced electrical measurements. Educationally this grant finically supported, a project scientist, an Assistant Professor, 2 post-doctoral researchers, 7 graduate students, and 2 undergraduate research assistants. Research activities of several other students were indirectly supported through the use of AFOSR supported equipment, and materials produced using processes developed under this award.
