摘要

半导体异质结的能带偏移是设计电子和光电器件的关键参数。在这项工作中，我们报告了 Co3O4/3C-SiC p-n 异质结的制作以及 Co3O4/3C-SiC 异质结导带和价带偏移的测定。我们的结果表明，Co3O4/3C-SiC p-n 异质结呈现出 II 型带排列，导带偏移为 0.75 eV，价带偏移为 0.96 eV。这些实验发现对于设计和开发用于电子和光电应用的 3C-SiC 器件至关重要。

Determination of the conduction and valence band offsets at the Co3O4/3C-SiC p-n heterojunction

The band offsets of semiconductor heterojunctions are critical parameters for the design of electronic and optoelectronic devices. In this work, we report the fabrication of a Co3O4/3C-SiC p-n heterojunction and the determination of the conduction band and valence band offsets at the Co3O4/3C-SiC heterojunction. Our results reveal that the Co3O4/3C-SiC p-n heterojunction exhibits a type-II band alignment, with a conduction band offset of 0.75 eV and a valence band offset of 0.96 eV. These experimental findings are crucial for the design and development of 3C-SiC devices for electronic and optoelectronic applications.

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.
