Abstract

High-TC cuprate superconductors' growth conditions and their incompatibility with some of the most standard nanofabrication approaches make their large-scale integration with 2D materials (such as graphene, transition metal dichalcogenides, and other Van der Waals materials) much more difficult than for conventional, metallic superconductors. Here, we address this challenge and develop an approach based on pulsed laser deposition that allows the growth of the 2D semiconductor MoS2 on the archetypal high-TC superconductor YBa2Cu3O7−x. This yields functional heterostructures in which the individual constituents' properties are preserved and that show superconducting coupling across their interface. The developed approach paves the way for large-scale 2D semiconductor co-integration with high-TC superconductors toward the study and leverage of the superconducting proximity effect in hybrid devices.

在高导磁超导 YBa2Cu3O7 上大规模集成 MoS2 以实现约瑟夫森器件

高热导率杯状超导体的生长条件及其与一些最标准的纳米制造方法的不兼容性，使其与二维材料（如石墨烯、过渡金属二卤化物和其他范德华材料）的大规模集成比传统金属超导体困难得多。在此，我们针对这一挑战，开发了一种基于脉冲激光沉积的方法，可在典型的高热导率超导体 YBa2Cu3O7-x 上生长二维半导体 MoS2。这就产生了功能性异质结构，其中单个成分的特性得以保留，并在它们的界面上显示出超导耦合。所开发的方法为大规模二维半导体与高导热系数超导体的共融铺平了道路，有助于研究和利用混合器件中的超导邻近效应。

期刊介绍： Applied Physics Letters (APL) features concise, up-to-date reports on significant new findings in applied physics. Emphasizing rapid dissemination of key data and new physical insights, APL offers prompt publication of new experimental and theoretical papers reporting applications of physics phenomena to all branches of science, engineering, and modern technology. In addition to regular articles, the journal also publishes invited Fast Track, Perspectives, and in-depth Editorials which report on cutting-edge areas in applied physics. APL Perspectives are forward-looking invited letters which highlight recent developments or discoveries. Emphasis is placed on very recent developments, potentially disruptive technologies, open questions and possible solutions. They also include a mini-roadmap detailing where the community should direct efforts in order for the phenomena to be viable for application and the challenges associated with meeting that performance threshold. Perspectives are characterized by personal viewpoints and opinions of recognized experts in the field. Fast Track articles are invited original research articles that report results that are particularly novel and important or provide a significant advancement in an emerging field. Because of the urgency and scientific importance of the work, the peer review process is accelerated. If, during the review process, it becomes apparent that the paper does not meet the Fast Track criterion, it is returned to a normal track.
