Studies on Pairing Symmetry and Normal-State Properties of Single-Layer T12Ba2CuO6+ Superconductors

这个GOALI实验研究项目涉及新的基础实验，探索最简单的铜高Tc超导体的超导性质，这些超导体每单元电池含有一个CuO2平面。本课题有两个方面，一是在三晶和其他衬底上生长Tl2201的优异外延膜。这将由纽约州立大学布法罗分校的PI执行。第二项任务是在IBM进行一组细微的测量，由项目中的IBM co-PI监督。这些测量将包括但不限于使用最先进的扫描SQUID显微镜进行测量。这些测量的目的是阐明超导的性质和优良单层样品中有序参数的对称性。这种样品的选择避免了铜链和层间相互作用的复杂性，使相关理论的测试更加透明。该研究将涉及一名博士后研究员，他将在两个地点接受良好的培训，有利于未来在工业、政府或学术界的职业生涯。这项工作本质上是跨学科的，并得到了美国国家科学基金会数学和物理科学理事会多学科活动办公室的部分支持。该实验研究项目属于“与工业界学术联络资助机会”（GOALI）的范畴，旨在促进学术界和工业界研究人员之间的合作。这个GOALI实验研究项目是关于在最简单的铜高Tc超导体中探测超导性质的基础实验，这些超导体每单元电池含有一个CuO2平面。该项目有两个方面，一是在三晶和其他衬底上生长Tl2201的优异外延膜。这将由纽约州立大学布法罗分校的PI执行。第二项任务是在IBM进行一组细微的测量，由项目中的IBM co-PI监督。这些测量将包括但不限于使用最先进的扫描SQUID显微镜进行测量。这些测量的目的是阐明超导的性质和优良单层样品中有序参数的对称性。这种样品的选择避免了铜链和层间相互作用的复杂性，使相关理论的测试更加透明。该研究将包括一名博士后研究员，他将接受良好的培训，有利于未来在工业、政府或学术教学和研究方面的职业生涯。这项工作本质上是跨学科的，并得到了美国国家科学基金会数学和物理科学理事会多学科活动办公室的部分支持。＊＊＊

w:\awards\awards96\*.doc 9801834 Ren This GOALI experimental research project is concerned with new basic experiments probing the nature of superconductivity in the simplest cuprate high Tc superconductors, those containing one CuO2 plane per unit cell. The project has two aspects, the first being growth of excellent epitaxial films of Tl2201 on tri- crystal and other substrates. This will be performed by the PI at SUNY Buffalo. The second task is a set of subtle measurements to be made at IBM supervised by the IBM co-PI's in the project. These measurements will include but not be limited to measurements using a state-of-the-art scanning SQUID microscope. The measurements are designed to clarify the nature of superconductivity and the symmetry of the order parameter in excellent single layer samples. This choice of samples avoids complications of copper chains and interlayer interactions, to enable more transparent tests of the relevant theories. The research will involve a postdoctoral researcher who will receive excellent training at both locations, beneficial to a future career in industry, government or academia. This work is interdisciplinary in nature and is supported in part by the Office of Multidisciplinary Activities in the Mathematical and Physics Sciences Directorate at NSF. %%% This experimental research project is in the category of Grant Opportunities for Academic Liaison With Industry (GOALI), which fosters collaboration between academic and industrial researchers.
