HarwellXPS Development 2022

我们寻求扩展国家光电子能谱研究机构(Harwell XPS，www.harwell xps.uk)提供的设施，以满足社区使用该中心的更广泛需求，而不仅仅是光电子能谱，从而提高服务的影响。我们将购买两个提供地形信息的系统，以补充XPS提供的表面化学信息。首先，一个可以与XPS精确同步的扫描电子显微镜系统，以便将主体成分和局部形貌与表面化学相关联；第二，一个光学剖面仪，用于研究XPS深度剖析中常用的蚀刻凹陷现象，从而使准确的深度信息与XPS化学信号相关联。最后，我们将购买一个电化学站，使所有Harwell XPS用户能够充分利用现有的独特样品保持器来研究不同电位下的样品。选定的设备基于各种证据来源，这些证据确定了两个领域的需求：(1)能源材料，包括电池和电容器。随着各方面技术的日益电动化，迫切需要开发新材料来提高清洁能源的生产和储存。这是法拉第研究所服务的一个研究领域，Harwell XPS的扩展将使两个机构之间的进一步接触成为可能。(2)新技术的新材料：随着我们的技术变得更加复杂，它对所使用的材料提出了越来越严格的要求。开发满足这些需求的新材料取决于我们对有关材料的性质和行为的了解。这些新设施将使Harwell XPS能够为研究人员提供一系列显著增强的研究材料的工具。

We seek to expand the facilities offered by the National Research Facility in photoelectron spectroscopy (HarwellXPS, www.harwellxps.uk) to address the wider needs of communities using the centre beyond simply photelectron spectroscopy and thereby improve the impact of the service. We will purchase two systems that provide topographical information that complements the surface chemical information provided by XPS. Firstly, a SEM system that can be precisely synced with the XPS so that bulk composition and local topography can be correlated with the surface chemistry; secondly an optical profiler to study the etch cratering commonly used in XPS depth profiling that will allow accurate depth information to correlate with the XPS chemical signals. Finally, we will purchase an electrochemical station that will enable all HarwellXPS users to make full use of the unique sample holder already available to study samples under different potentials. The equipment selected is based upon a variety of sources of evidence that have identified two areas of need: (1) Energy materials, including batteries and capacitors. With the increasing electrification of all aspects of technology, there is an urgent need to develop new materials to improve clean energy production and storage. This is a research area served by the Faraday Institute and the extension of HarwellXPS will enable further engagement between the two institutions.(2) New materials for new technologies: As our technology grows more sophisticated it is placing increasingly stringent demands on the materials employed. Developing new materials to meet these demands depends on improving our understanding of the nature and behaviour of the materials concerned. The new facilities will allow HarwellXPS to offer researchers a significantly enhanced array of tools to study materials.
