高压下多元硼碳基高温超导体的研究进展
Research Progress in Multi-Boron-Carbon-Based High-Temperature Superconductors under High Pressures
摘要
Abstract
Superconductors would exhibit unique quantum properties below the critical transition temperatures,including zero-resistance and complete diamagnetism(the Meissner effect)and have potential revolutionary application in fields of energy transmission and transportation.Therefore,the exploration of high-temperature superconductors with transition temperature exceeding the liquid nitrogen boiling point(77 K)has remained a central issue in condensed matter physics.Based on the Bardeen-Cooper-Schrieffer(BCS)theoretical framework,more studies reveal that the light-element compounds with strong covalent bonds(like boron-carbon-based systems)can also exhibit strong electron-phonon coupling,which is similar to the hydrogen rich superconductors.Moreover,it can show high superconducting transition temperatures and can display excellent structural stability under sub-megabar pressures.For example,the MgB2 and its derivatives,such as layered boron-carbon superconductors,sodalite-like cage-structured boron-carbon systems,and other boron-carbon-based superconductors,have received more attention in the field of boron-carbon-based superconductors.In this paper,we reviewed the recent progresses in boron-carbon-based superconductors,systematically analyzed the mechanism of its superconductivity,and discuss future challenges in discovering more high-temperature superconductors within this material family.关键词
