Multifunctional Scanning Microscopy

基础物理、先进材料和纳米级新器件的研究需要最先进的表征和优化工具。利兹大学在纳米材料方面的研究活动非常活跃，分为物理学院（自旋电子学、生物物理学和软物质）、化学学院（纳米合成、结晶、自旋交叉分子）和工程学院（多铁材料和用于催化和能源的纳米材料）。这意味着16名学者，50多名博士生和博士后，以及每年数百万英镑的研究收入可以从这个设施中受益。密集的研究活动延伸到约克郡（约克，谢菲尔德）和英国北部（曼彻斯特，诺丁汉，达勒姆，格拉斯哥）的其他世界级团体。该项目将通过为具有附加功能的新型、最先进的多功能低温SPM提供资金来加强这一努力，其中一些功能将与制造商合作开发，并且在英国或世界上是独一无二的，例如近场磁成像、亚开尔文MFM微波应用或扫描纳米squid技术。通过成为一个国家设施，该项目还旨在将该仪器用作科学催化剂，将对表面和纳米尺度科学有共同兴趣的不同领域的领先研究人员聚集在一起。利兹大学将开展的核心研究包括：*纳米器件。我们的重点将是纳米级自旋电子器件，包括非局部自旋阀中的纯自旋电流、薄膜和片状器件中的拓扑超导性、沉积在压电衬底上的磁道中的畴壁传播、拓扑和自旋霍尔效应以及分子界面中的门控近藤散射等实验。然而，我们也将扩展在这些主题的界面上出现的能力和合作，例如自旋交叉分子器件，扫描SQUID检测稀释半导体中的自旋电流和反铁磁器件的高频光谱。*薄膜：利兹处于薄膜生长的前沿，在skyrion材料，钇铁石榴石，磁热涂层和金属富勒烯界面等方面取得了开创性的成果。SPM将有助于保持我们世界一流的声誉，并在这些系统中进行新颖的实验。这将通过在利兹和其他地方的新型多功能沉积设施来扩展，以建立在多铁质，拓扑绝缘体薄膜和Heusler合金等方面的合作。*软物质和多功能应用。纳米材料已经彻底改变了广泛的技术过程；从使用纳米颗粒的生物成像和催化，到聚合物和钙钛矿的能源生成，膜中的生物力学等等。该设施将通过允许具有转化潜力的非核心纳米材料的表征时间共享来为这项研究做出贡献。在英格兰北部（曼彻斯特，沃里克）有低温，磁场SPM系统。然而，要在纳米材料领域领先世界，我们需要一种独特的、独立的、多功能的能力，能够对研究前沿的快速变化做出反应。

esearch in fundamental physics, advanced materials and novel devices at the nanoscale requires state of the art tools for characterisation and optimisation. There is a very strong research activity on nanomaterials at Leeds divided between the School of Physics (spintronics, biophysics and soft matter), the School of Chemistry (nano-synthesis, crystallisation, spin-crossover molecules) and the Faculty of Engineering (multiferroics and nano-materials for catalysis and energy). This represents sixteen academics , over fifty PhD students and postdocs and several million pounds in research income per year that can benefit from this facility. The intensive research activity extends to other world-class groups in Yorkshire (York, Sheffield) and northern Britain (Manchester, Nottingham, Durham, Glasgow). This project will strengthen this endeavour by providing funds for a new, state of the art multifunctional low temperature SPM with added capabilities -some of which will be developed in collaboration with the manufacturer and unique in the UK or the world, such as near-field magnetic imaging, microwave application at sub-Kelvin MFM or scanning nano-SQUID technology. By becoming a national facility, the project aims as well to use the instrument as a science catalyst, bringing together leading researchers in different fields with a common interest in surface and nanoscale science. The core studies to be carried from at Leeds include:* Nanodevices. Our focus will be in nanoscale spintronic devices, including experiments such as pure spin currents in non-local spin valves, topological superconductivity in thin film and flake devices, domain wall propagation in tracks deposited on piezoelectric substrates, topological and spin Hall effects and gate-operated Kondo scattering in molecular interfaces. However, we will also extend the capabilities and collaborations emerging at the interface of these topics, such as spin-crossover molecular devices, scanning SQUID detection of spin currents in diluted semiconductors and high-frequency spectroscopy of antiferromagnetic devices. * Thin films: Leeds is at the forefront of thin film growth, with pioneering results in skyrmion materials, yttrium iron garnet, magneto-caloric epilayers and metallo-fullerene interfaces amongst many others. The SPM will contribute to maintain our world-class reputation and carry novel experiments in these systems. This will be expanded by novel multi-functional deposition facilities in Leeds and elsewhere to establish collaborations in multiferroics, topological insulator thin films and Heusler alloys amongst others.* Soft matter and multifunctional applications. Nanoscale materials have revolutionised a wide range of technological processes; from bio-imaging and catalysis using nanoparticles, to energy generation with polymers and perovskites, biomechanics in membranes and many others. The facility will contribute to this research by allowing a time-share for the characterisation of non-core nanomaterials with transformative potential.There are low temperature, magnetic field SPM systems in the north of England (Manchester, Warwick). However, to lead the world in nanomaterials, we need an exclusive, stand alone and versatile capability that can react to the fast changes at the cutting edge of research.
