超导现象早在1911年就为世人所知. 基于超导材料和超导技术广阔的应用前景, 一百多年来来自物理、化学、材料等不同领域的研究者们一直为发现新的、高超导转变温度(甚至室温)的超导材料而不断努力. 同时, 超导材料的表界面研究工作也越来越受到关注. 本文首先介绍了过去国内外研究者在铜基氧化物超导材料表面的一些分子吸附研究工作, 随后总结了最近在超导薄膜体系中界面效应对提高超导转变温度及其研究超导机制的意义, 着重揭示了表面/界面在超导研究和发展中的重要性.

Superconductivity was discovered in 1911. Due to the greatly potential applications of superconducting materials and superconducting techniques, researchers from physical, chemical, and materials sciences have been working hard to achieve new superconducting materials with high superconducting transition temperature and even up to room temperature. Meanwhile, the surface/interface issue in superconducting materials has been paid more and more attention. In this paper, a brief summary is made about the previous works on the surface adsorption of copper-oxide superconductors. Then, interface effect is introduced and demonstrated to play an important role in increasing transition temperature and clarifying the superconductivity mechanism in superconducting films. The importance of the surface/interface effect is largely highlighted in the research and development of the superconducting materials.

Key words: superconductivity, oxide superconductor, superconducting film, surface adsorption, interface effect
