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.

在过去的几年中，对具有过渡温度的铜氧化物超导体（TC）高达125K，但高TC的起源和异常正常状态的起源仍然未知。 我们建议准备较低TC的氧化铜SC并测量其物理特性。 将对具有系统变化的掺杂（载体）的高质量晶体进行测量。 目的是阐明所有氧化铜超导体中超导性和异常状态的性质的机制。
