The crystal chemistry of the alkaline-earth cupric oxides stabilized at high pressure was studied by high-resolution electron microscopy. Two families of superconductors, (Ca1-ySry)1-xCuO2 and Srn+1CunO2n+1+delta (n = 1, 2), and one series of semiconductors, Srn-1Cun+1O2n, are reported. Their structural characteristics are systematically interpreted on the basis of the simple infinite-layer structure seen in SrCuO2. Microstructures and their relevance to high-Tc superconductivity are discussed, particularly in the alkaline-earth-deficient infinite-layer phase.
通过高分辨率电子显微镜研究了在高压下稳定存在的碱土铜氧化物的晶体化学。报道了两类超导体，(Ca1-ySry)1-xCuO2和Srn+1CunO2n+1+δ（n = 1, 2），以及一系列半导体，Srn-1Cun+1O2n。基于在SrCuO2中观察到的简单无限层结构，系统地解释了它们的结构特征。讨论了微观结构及其与高温超导性的关系，特别是在碱土缺乏的无限层相中。
