钻石中的一颗美丽的宝石是绝缘体。然而,硼掺杂可以诱导金刚石具有半导体、金属和超导性质。当硼浓度大于3 × 1020 cm−3时,金刚石进入金属区,并在低温下表现出超导性。利用ARPES、XAS、NMR、IXS、输运和磁性测量等分析了金属-绝缘体的跃迁和超导性。本文综述了金刚石超导体作为半导体中的一种特殊超导体的物理性质和作用机理。
A beautiful jewel of diamond is insulator. However, boron doping can induce semiconductive, metallic and superconducting properties in diamond. When the boron concentration is tuned over 3 × 1020 cm−3, diamonds enter the metallic region and show superconductivity at low temperatures. The metal–insulator transition and superconductivity are analyzed using ARPES, XAS, NMR, IXS, transport and magnetic measurements and so on. This review elucidates the physical properties and mechanism of diamond superconductor as a special superconductivity that occurs in semiconductors.
