具有原子尺度厚度的二维超导体

Two-dimensional Superconductors with Atomic-scale Thicknesses

Takashi Uchihashi

摘要:

本文主要从实验角度评述了原子尺度二维超导体的研究进展。这里讨论的超导系统涉及各种材料和形式:半导体表面的元素金属氧化物薄膜和原子层;由铜酸盐、钙钛矿氧化物和稀土金属重费米子化合物制成的异质结构的界面和超晶格;双电层晶体管的界面;石墨烯和过渡金属二硫属化物的原子片;分别在氧化物和金属表面上的硒化铁和有机导体。独特的现象所产生的最终二维系统和背后的物理进行了讨论。

英文摘要:

Recent progress in two-dimensional superconductors with atomic-scale thicknesses is reviewed mainly from the experimental point of view. The superconducting systems treated here involve a variety of materials and forms: elemental-metal ultrathin films and atomic layers on semiconductor surfaces; interfaces and superlattices of heterostructures made of cuprates, perovskite oxides, and rare-earth metal heavy-fermion compounds; interfaces of electric-double-layer transistors; graphene and atomic sheets of transition-metal dichalcogenide; iron selenide and organic conductors on oxide and metal surfaces, respectively. Unique phenomena arising from the ultimate two-dimensionality of the system and the physics behind them are discussed.
