This proposal requests funds to support four graduate students applying novel x-ray diffraction techniques to solve a variety of timely condensed matter physics problems. The research involves using both the University of Guelph in-house x-ray diffraction infrastructure as well as high performance synchrotron user facilities such as the Canadian Light Source. The group will focus on both applying and developing high resolution powder diffraction, single crystal diffraction, surface diffraction and high-resolution pair distribution function methods. These are all methods that the Kycia group has developed much experience applying over the years and allow them unprecedented atomic resolution of nanoparticle, amorphous and polycrystalline materials. This work has applications related to optoelectronics, magnetic storage, microelectronics, catalysis, and fuel cells. This work is expected to make great progress in the area of x-ray diffraction methods.

该提案请求资金支持四名研究生应用新型 X 射线衍射技术来解决各种及时的凝聚态物理问题。该研究涉及使用圭尔夫大学内部 X 射线衍射基础设施以及高性能同步加速器用户设施，例如加拿大光源。该课题组将重点关注高分辨率粉末衍射、单晶衍射、表面衍射和高分辨率对分布函数方法的应用和发展。这些都是 Kycia 团队多年来积累的丰富经验的方法，使他们能够对纳米粒子、非晶态和多晶材料进行前所未有的原子分辨率。这项工作具有与光电子学、磁存储、微电子学、催化和燃料电池相关的应用。这项工作有望在 X 射线衍射方法领域取得重大进展。
