This award is jointly supported by the Major Research Instrumentation and the Chemistry Research Instrumentation Programs. Boston University is acquiring X-ray photoelectron spectrometer (XPS) with low-energy inverse photoelectron spectroscopy, ultraviolet photoelectron spectroscopy, and Raman spectroscopy capabilities to support the research of Professor Xi Ling and colleagues Keith Brown, Malika Jeffries-EL, and Kevin Smith. The instrument facilitates research in the areas of chemistry, engineering, and physics. XPS spectra are produced by irradiating a specimen with X-rays with sufficient energy to eject electrons, and the kinetic energy of the electrons is measured and subsequently related to their binding energy. These data can be related to the chemical elements in the sample as well as to their bonding environment. This instrument enhances the educational, research, and teaching efforts of students in many departments as well as provides accessibility for use at nearby institutions. Students from diverse backgrounds utilize the instrument in their research and research training. Accessibility is enhanced through its integration in two courses.The award for the XPS is aimed at enhancing research and education at all levels, especially in areas such as functional materials and structures. This includes investigations of the electronic band structure of two dimensional materials and heterostructures as well as the optoelectric properties of organic semiconducting molecules relevant to solar technology. In addition, XPS is used to determine the electronic structure of low dimensional correlated solids to understand their optical, electrical, magnetic, structural, and chemical properties. It is also used to probe the surface chemistry and dynamics of nanostructured polymer surfaces.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

该奖项由主要的研究工具和化学研究工具计划共同支持。波士顿大学正在获取具有低能量逆光电光谱，紫外光光谱光谱和拉曼光谱功能的X射线光电子光谱仪（XPS），以支持XI Ling和Malika Jeffries-Elies-Elies-El和kingvin Smelth的XI Ling和Malika Jeffries-El和smern Smith教授的研究。该仪器促进了化学，工程和物理学领域的研究。 XPS光谱是通过辐照带有足够能量来喷射电子的X射线的样品来产生的，并测量电子的动能并随后与它们的结合能相关。这些数据可能与样品中的化学元素以及它们的键合环境有关。该工具可以增强许多部门学生的教育，研究和教学工作，并为附近机构提供可访问性。来自不同背景的学生在研究和研究培训中利用该工具。 XPS的奖项旨在增强各个级别的研究和教育，尤其是在功能材料和结构等领域。这包括研究两维材料和异质结构的电子带结构，以及与太阳能技术相关的有机半导体分子的光电特性。此外，XPS用于确定低维相关固体的电子结构，以了解其光学，电气，磁性，结构和化学性质。它也用于探测纳米结构聚合物表面的表面化学和动力学。该奖项反映了NSF的法定任务，并且使用基金会的知识分子优点和更广泛的影响评估标准，认为值得通过评估来获得支持。
