Women have made significant contributions to applied physics research and development, and their participation is vital to continued progress. Recognizing these contributions is important for encouraging increased involvement and creating an equitable environment in which women can thrive. This Roadmap on Women in Applied Physics, written by women scientists and engineers, is intended to celebrate women’s accomplishments, highlight established and early career researchers enlarging the boundaries in their respective fields, and promote increased visibility for the impact women have on applied physics research. Perspectives cover the topics of plasma materials processing and propulsion, super-resolution microscopy, bioelectronics, spintronics, superconducting quantum interference device technology, quantum materials, 2D materials, catalysis and surface science, fuel cells, batteries, photovoltaics, neuromorphic computing and devices, nanophotonics and nanophononics, and nanomagnetism. Our intent is to inspire more women to enter these fields and encourage an atmosphere of inclusion within the scientific community.

“…Significant progress has been made over the past three decades on the YBCO thin film quality, junction fabrication techniques and control of the junction parameters, driven primarily by research and development of superconducting quantum interference devices (SQUIDs) [6]. The research group at CSIRO has developed and matured a YBCO/MgO step-edge Josephson junction technology [54] and many novel HTS devices and application systems based on this technology [55], [56]. The advancement of HTS microwave and millimeter wave active devices and circuits based on this YBCO/MgO step-edge junction technology will be presented later sections.…”

High temperature (high-Tc) superconductors (HTS) have found many applications in the last two decades. To microwave researchers and engineers, the ultra-low surface resistance of the thin-film HTS materials at microwave and millimeter frequencies and the highly non-linear Josephson junctions are of particular interest. The former can be exploited in the design and fabrication of passive microwave components and circuits with superior performance, and the latter can be exploited to create many novel active HTS devices. This paper provides an overview of the state-of-art development of HTS devices and circuits for microwave and mm-wave communication front-end receiver systems. The paper is particularly focused on the latest advancement of HTS Josephson junction based active devices, monolithic microwave integrated circuits (MMIC), and whole receiver systems integrated with cryocoolers.INDEX TERMS Filters, high temperature superconductors (HTS), Josephson junction, mixers, receivers.

“…[ 16–20 ] Various devices, including step‐edges, Josephson junction (JJ)‐based devices, and superconducting quantum interference devices (SQUIDs), are made with a thin film of YBCO grown on MgO substrates. [ 21–27 ] The surface quality of the MgO substrate and the deposition circumstances has a significant impact on the quality of these YBCO thin film‐based devices. To deposit a good quality thin films, the surface of the MgO substrate must be free of impurities, such as hydroxides, carbonates, and adventitious carbon, as well as it should be atomically flat with high crystalline order.…”

Herein, the combined impact of ion beam milling and postannealing treatment on the transport properties of deposited YBa2Cu3Ox (YBCO) thin film and fabricated step‐edge Josephson junction (JJ) on degraded MgO (100) substrates are investigated, and the obtained results of the YBCO thin film and fabricated step‐edge JJ on treated MgO (100) substrate are compared with the YBCO film and step‐edge junction on a fresh MgO substrate. Structural study reveals the formation of c‐axis‐oriented YBCO thin film on revived MgO substrate which is very much comparable with the YBCO film on fresh substrate. Atomic force microscopy (AFM) technique is used to confirm the step heights of the fabricated step‐edges on fresh, revived, and degraded MgO substrates. After the treatment, the surface roughness of MgO substrate has reduced from 56 to 1.06 nm which is comparable with the fresh MgO (100) substrate. The acquired values of critical temperatures for as‐deposited YBCO thin film on fresh and revived MgO substrates are 89.1 and 88.3 K, respectively, whereas these values are 85.8 and 85.7 K for the fabricated step‐edge junction microbridges on these deposited thin films. For both the fabricated step‐edge junction on the revived and fresh MgO substrate, the superconductor–normal metal–superconductor‐type JJ is confirmed.
