The last 15-20 years have witnessed a remarkable growth in the field of terahertz (THz) frequency science and engineering, which has now become a vibrant, international, cross-disciplinary research activity. Yet, despite long-standing efforts by the international community, difficulties remain in accessing and exploiting this central region of the electromagnetic spectrum (300 GHz to 10 THz in frequency) owing to the lack of compact, solid state, sources. Notwithstanding these difficulties, the range of potential applications for the THz frequency range of the spectrum is enormous, and includes: astronomy; pharmaceutical process monitoring; wireless communications; dermatological imaging; and the study of condensed matter physics and nanostructures. Equally, much progress has been made in developing THz sources, with a specific international focus being on the development of THz quantum cascade lasers (QCLs), which were first demonstrated in 2002. Many exciting challenges face THz researchers. Of particular interest to me are questions such as:1) How can we measure condensed matter systems (whether semiconducting, superconducting or magnetic), and nanostructures, in the THz frequency range? What new, fundamental, physics will be revealed, especially at cryogenic temperatures and at high magnetic fields? 2) Can one engineer THz QCLs both photonically and electronically to make a source that is as ubiquitous as solid state, semiconductor devices are in other parts of the spectrum? Can THz QCLs meet the stringent requirements of space-borne technology for THz astronomy? 3) Can THz radiation be used to study biological materials, especially at a cellular level? It is undoubtedly true that to maximise impact across the THz spectral range, there is a requirement for inter-disciplinary collaboration between researchers across science and engineering. This presents many challenges, and it is such challenges that I will explore through this Fellowship. The Fellowship will free up my time from current University teaching/administrative commitments, and allow me to focus on addressing such key issues, and hence define the international agenda for the next decade and beyond in the field of THz science and engineering. It will allow me to have extended visits to leading international researchers, in a way that it is not normally possible with University commitments. From these visits, I will not only develop new research activities in the THz field, but also understand how some of the world's leading researchers develop creative ideas, assemble successful research teams from academic staff through to graduate students, and undertake cross-disciplinary research outside the traditional boundaries. I will then take these ideas, combine them with the metods that I have used to build research teams and projects to date, and use professional organisations within the UK to bring new approaches for developing creativity to my research.

在过去的15 - 20年中，Terahertz（THZ）频率科学与工程领域的增长显着增长，该领域现在已成为一项充满活力的，国际，跨学科的研究活动。然而，尽管国际社会的长期努力，但由于缺乏紧凑的，固态，来源，电磁频谱的这个中央区域（频率为300 GHz至10 THz）仍然存在困难。尽管存在这些困难，但频谱的THZ频率范围的潜在应用范围是巨大的，包括：天文学；药物过程监测；无线通信；皮肤病学成像；以及凝结物理和纳米结构的研究。同样，在开发THZ来源方面已经取得了很多进展，特定的国际重点是在2002年首次证明的THZ量子级联激光器（QCLS）的发展。许多令人兴奋的挑战面临着THZ研究人员。我特别感兴趣的是：1）诸如：1）如何在THZ频率范围内测量凝结物质系统（无论是半导体，超导或磁性）和纳米结构？将揭示哪些新的，基本的物理学，尤其是在低温温度和高磁场下？ 2）一位工程师可以通过光子和电子方式工程QCL，以使源与固态一样无处不在，半导体设备在频谱的其他部分？ THZ QCL可以满足THZ天文学的太空发展技术的严格要求吗？ 3）可以使用THZ辐射研究生物材料，尤其是在细胞水平上？毫无疑问，为了最大程度地提高THZ光谱范围的影响，需要在科学和工程之间进行研究人员之间的跨学科合作。这提出了许多挑战，这是我将通过这一奖学金探索的挑战。奖学金将使我的时间从当前的大学教学/行政承诺中释放出来，并让我专注于解决此类关键问题，因此定义了未来十年及以后的国际议程，在THZ Science and Engineering领域。这将使我能够对领先的国际研究人员进行扩展访问，而大学承诺通常不可能。从这些访问中，我不仅将在THZ领域开发新的研究活动，而且还了解一些世界领先的研究人员如何发展创意思想，组装从学术人员到研究生的成功研究团队，并在传统边界之外进行跨学科研究。然后，我将采用这些想法，将它们与迄今为止用于建立研究团队和项目的Metods结合使用，并使用英国境内的专业组织为我的研究带来了新的方法来发展创造力。
