Copper oxide superconductors with transition temperature (Tc) as high as 125K have been much studied during the past few years but the origin of the high Tc and that of the unusual normal state are still unknown. We propose to prepare copper oxide scs with lower Tc and to measure their physical properties. Measurements will be made on high-quality crystals with a systematic variation of doping (carriers). The objective is to elucidate the mechanism for superconductivity and the nature of the anomalous normal state in all copper oxide superconductors.

在过去的几年里，人们对转变温度高达125K的氧化铜超导体进行了大量的研究，但高转变温度和异常正常态的起源仍不清楚。我们建议制备低T_c的氧化铜SCS，并对其物理性能进行测试。测量将在具有系统变化的掺杂(载流子)的高质量晶体上进行。其目的是阐明所有铜氧化物超导体中超导电性的机制和反常正常态的性质。
