本文综述了碳基材料的新超导相。在过去的十年中，新的碳基超导体已经通过使用嵌入化学，静电载流子掺杂和表面验证技术得到了广泛的发展。这些材料的超导转变温度Tc已迅速提高，超导体的种类已增加。本文全面介绍了石墨、石墨烯和碳氢化合物超导体，以及基于这些材料的高温超导体的发展前景和存在的问题。碳基超导体显示出各种有趣的行为，例如Tc的正压力依赖性。目前，有关超导体的实验资料还不充分，理论处理也不完整。特别是，石墨烯和碳氢化合物超导体的实验结果仍然缺乏。因此，为了凝聚态物理学的发展，详细回顾实验结果并介绍理论方法是非常重要的。此外，本文还介绍了本课题组最近在碳氢化合物超导体方面的实验结果。因此，这篇评论文章可能会提供一个提示，设计新的碳基超导体表现出更高的Tc和有趣的物理特性。
This article reviews new superconducting phases of carbon-based materials. During the past decade, new carbon-based superconductors have been extensively developed through the use of intercalation chemistry, electrostatic carrier doping, and surface-proving techniques. The superconducting transition temperature Tc of these materials has been rapidly elevated, and the variety of superconductors has been increased. This review fully introduces graphite, graphene, and hydrocarbon superconductors and future perspectives of high-Tc superconductors based on these materials, including present problems. Carbon-based superconductors show various types of interesting behavior, such as a positive pressure dependence of Tc. At present, experimental information on superconductors is still insufficient, and theoretical treatment is also incomplete. In particular, experimental results are still lacking for graphene and hydrocarbon superconductors. Therefore, it is very important to review experimental results in detail and introduce theoretical approaches, for the sake of advances in condensed matter physics. Furthermore, the recent experimental results on hydrocarbon superconductors obtained by our group are also included in this article. Consequently, this review article may provide a hint to designing new carbon-based superconductors exhibiting higher Tc and interesting physical features.
