U.S.-Finland Cooperative Research: Fermi Surface Determination of Quasicrystal via Compton Scattering

9978382莫斯该奖项支持西蒙·莫斯、保罗·周、约瑟夫·库利克以及休斯顿大学的一名研究生，他们与芬兰赫尔辛基大学X射线实验室的汉努·佩卡·索尔蒂合作。该项目将侧重于确定费米表面的存在，并利用选定准晶和相关金属间结构的康普顿散射测量其尺寸。一个长期的目标是了解复杂导体的输运和电子性质，最终可能包括金属玻璃、导电氧化物和磁性材料。该合作利用了准晶(休斯顿大学、艾姆斯实验室和纽约城市学院)和康普顿散射(赫尔辛基大学)领域的研究人员的个人专业知识。合作给研究界带来的总体科学利益将是提供有关合金物理的重要信息，由于准晶的复杂性质和高能康普顿散射所需的复杂技术，任何个人小组都难以收集和分析这些信息。

9978382MossThis award supports Simon Moss, Paul Chow, Joseph Kulik, and a graduate student from the University of Houston in a collaboration with Hannu Pekka Suortti at the X-Ray Laboratory at the University of Helsinki, Finland. The project will focus on establishing the existence of a Fermi surface and measuring its dimensions using Compton scattering from selected quasicrystals and related intermetallic structures. A long-range goal is to understand the transport and electronic properties of complex conductors which can eventually include metallic glasses, conducting oxides, and magnetic materials. The collaboration draws on the individual expertise of researchers in the fields of quasicrystals (U. of Houston, Ames Laboratory, and City College of New York) and Compton scattering (U. of Helsinki). The overall scientific benefit of the collaboration to the research community will be to provide important information on alloy physics which would be difficult for any individual group to collect and analyze due to the complicated nature of quasicrystals and the sophisticated techniques required for high-energy Compton scattering.
