项目摘要

The discovery of new correlated-electron ground states such as new types of superconductor and magnet that may underpin future technologies, e.g. for computer memories, is a challenge requiring the combined skills of chemists, physicists, materials scientists and engineers. Exciting discoveries in recent years have included high temperature cuprate and pnictide superconductors, and colossal magnetoresistance (CMR) manganites. The prediction of such properties is, however, notoriously difficult and many high impact discoveries have been made serendipitously e.g. superconductivity in MgB2. Our more targeted approach is to use extreme conditions to facilitate the discovery of new electronic materials. High pressure-temperature synthesis provides dense new materials in which electron correlations are enhanced and may be altered by chemical doping. Careful tuning of low temperatures, high pressures and high magnetic fields can then be used to push materials to the tipping points where new electronic ground states form. The applicants have strong backgrounds in different disciplines that will be combined to achieve our ambitious goal of discovering new materials with notable properties. Support through this Platform award will add considerable value to the existing arrangement. It will ensure continuity for our core group of key staff and the essential research expertise that they bring. We will have the flexibility to respond to major developments and explore speculative but potentially rewarding new directions. It will provide a high profile for our electronic materials research group as a distinct entity within the broader programme of CSEC. Current international collaborations will be strengthened by involving the whole Platform team, and will facilitate new links to other internationally-leading groups. Inviting research lecturers and exchanging research staff with such groups will be a further benefit. The Platform award will also augment the cross-disciplinary nature of the training that we can provide to our students and PDRA's. Although they (and we) formally belong to three separate UoE Schools, working together in the same institute and henceforth as a common group will provide a stimulating atmosphere to generate new ideas and discoveries in electronic materials research.

新的相关电子基态的发现，例如新型超导体和磁体，可能支撑未来的技术，例如对于计算机存储器来说，这是一项挑战，需要化学家、物理学家、材料科学家和工程师的综合技能。近年来令人兴奋的发现包括高温铜酸盐和磷族元素超导体，以及巨磁阻（CMR）锰酸盐。然而，对这些特性的预测是出了名的困难，并且许多具有重大影响的发现都是偶然做出的，例如： MgB2 的超导性。我们更有针对性的方法是利用极端条件来促进新电子材料的发现。高压高温合成提供了致密的新材料，其中电子相关性得到增强，并且可以通过化学掺杂来改变。然后可以通过仔细调节低温、高压和高磁场将材料推至形成新电子基态的临界点。申请人在不同学科中拥有深厚的背景，这些背景将被结合起来，以实现我们发现具有显着性能的新材料的雄心勃勃的目标。通过该平台奖项提供的支持将为现有安排增加相当大的价值。它将确保我们的核心骨干团队及其带来的重要研究专业知识的连续性。我们将灵活地应对重大发展，并探索推测性但可能有益的新方向。它将为我们的电子材料研究小组作为 CSEC 更广泛计划中的一个独特实体提供高知名度。当前的国际合作将通过整个平台团队的参与得到加强，并将促进与其他国际领先团体的新联系。邀请研究讲师并与这些团体交流研究人员将是进一步的好处。该平台奖还将增强我们为学生和 PDRA 提供的培训的跨学科性质。尽管他们（和我们）正式属于三个独立的伦敦大学学院，但在同一个研究所一起工作，今后作为一个共同的团体，将为电子材料研究中产生新想法和新发现提供一种刺激的氛围。
