The context of the researchDiamond is a fantastic new material for the production of future generation high performance electronic devices. Understanding the fundamental operation of the surface of diamond at the atomic and quantum level is crucial for the ongoing development of diamond electronic device technology and forms the basis for this PhD research. The unique properties of diamond in particular make it ideal for the development of robust electronic systems for operation in extreme and hazardous environments such as for future satellite technologies, extra-terrestrial planetary exploration and long-haul space missions.Brief description of the context of the research including potential impact;Although diamond possesses many unique characteristics which make it highly attractive as an active semiconductor, difficulties associated with doping have restricted the ongoing development of a range of electronic, sensing, optical and quantum technologies. This work will investigate the physical, chemical and electrical processes at play at the diamond surface to develop greater understanding and exploitation potential of surface transfer doping (STD) in diamond. Establishing a robust and high performance STD process in diamond will catalyse research in an wide area or diamond based applications with the primary focus being high power, robust electronics for this work.Aims and objectivesDevelop an atomistic model for the STD process at the interface between diamond and a range of electron acceptor materials.Explore alternative surface terminations of diamond both theoretically and by experimentation to investigate their potential application for advanced STD.Generate a detailed model for the sub-surface transport of charge with diamond and ascertain the maximum performance achievable in terms of carrier mobility and density. Novelty of the research methodologyThis research will combine cutting edge experimental diamond experimental work with atomistic modelling and simulation to bridge the gap between theory and practise in fundamental diamond electronic device research. The University of Glasgow are currently world leaders in the development of diamond device technology and this work will expand greatly upon and complement this research.Alignment to EPSRC's strategies and research areas:As part of the EPSRC remit for "RF and Microwave Devices", the proposed work strongly aligns with the EPSRC ICT shaping capability campaign and is highlighted as a priority research area for growthIts potential applications and benefitsA range of diamond technologies currently in development and yet to be established will benefit from this work. Specifically this research will impact the development of high power, high frequency devices and systems for use in a range of future applications e.g. satellite communications, radar etc.Any companies or collaboratorsOliver Williams - Cardiff UniversityElement Six LtdAlex Talliare - University Paris 13

研究背景钻石是生产下一代高性能电子设备的一种奇妙的新材料。在原子和量子水平上了解钻石表面的基本操作对于钻石电子器件技术的持续发展至关重要，并构成本博士研究的基础。钻石的独特性质尤其使其非常适合于开发在极端和危险环境中运行的坚固的电子系统，例如未来的卫星技术、地外行星探索和长途太空任务。对研究背景的简要说明，包括潜在的影响；虽然钻石具有许多独特的特性，使其作为一种活性半导体具有极大的吸引力，但与掺杂有关的困难限制了一系列电子、传感、光学和量子技术的持续发展。这项工作将研究在钻石表面起作用的物理、化学和电子过程，以更好地了解和开发钻石表面转移掺杂(STD)的潜力。在钻石中建立强健和高性能的STD过程将促进广泛区域或基于钻石的应用的研究，主要焦点是高功率、坚固的电子学。目标和目标在钻石和一系列电子受体材料之间的界面上建立STD过程的原子模型。从理论和实验两个方面探索替代的钻石表面终端，以研究它们在先进的STD中的潜在应用。建立一个详细的模型来描述带金刚石的电荷的亚表面传输，并确定在载流子迁移率和密度方面所能达到的最大性能。研究方法的新颖性本研究将把尖端的实验钻石实验工作与原子建模和模拟相结合，以弥合基础钻石电子器件研究中理论与实践之间的差距。格拉斯哥大学目前在钻石器件技术的开发方面处于世界领先地位，这项工作将极大地扩展和补充这项研究。与EPSRC的战略和研究领域保持一致：作为EPSRC“射频和微波器件”任务的一部分，拟议的工作与EPSRC ICT成形能力运动密切相关，并被强调为增长的优先研究领域，其潜在应用和好处目前正在开发中，但尚未建立的一系列钻石技术将从这项工作中受益。具体地说，这项研究将影响高功率、高频设备和系统的发展，用于未来的一系列应用，如卫星通信、雷达等。任何公司或合作者奥利弗·威廉姆斯-卡迪夫大学Element Six Ltd.Alex Talliare-巴黎大学13
