Preparation and Properties of Low Tc Copper Oxide Single Crystals

这个项目涉及所谓的低温氧化铜超导体。研究的重点是电子掺杂的钕-铈-铜-氧体系。这项研究将在主要研究人员的实验室中对同一种单晶材料进行大量的物理测量。目的是为了更好地理解所有氧化铜超导体的超导机制和异常状态的性质。这项研究将补充高温氧化铜超导体的类似研究。对具有系统变化的掺杂剂的高质量单晶的测量应该能够实现这一目标，并且还可以更好地理解低掺杂下绝缘体到金属的转变。

This project deals with so-called low temperature copper oxide superconductors. The focus of research will be on the electron- doped neodyium-cerium-copper-oxygen system. The research will employ a substantial range of physical measurements on the same single crystal material grown in the principal investigators laboratory. The objective is to gain a better understanding of the mechanism of superconductivity and the nature of the anomalous state in all copper oxide superconductors. The research will complement similar investigations in the high temperature copper oxide superconductors. Measurements on high quality single crystals with a systematic variation of dopants should enable this goal to be achieved and also allow the insulator to metal transition at low dopant to be better understood.
