项目摘要

The history of II-VI metal-organic chemical vapour deposition (MOCVD) goes back as far as IIII-V MOCVD but has not had the traction in applications for lasers, LEDs and high frequency devices that has been experienced by III-V semiconductors. A new generation of MOCVD equipment can more fully exploit the potential of II-VI semiconductors and explore new oxides and chalcogenides in the exiting areas of III-VIs such as Ga2O3 and 2-D semiconductors such as MoS2. There is now a compelling case for the UK to have state-of-the-art MOCVD equipment for compound semiconductors (CS) covering oxide and chalcogenide materials that are not covered by existing centres such as the National Epitaxy Facility at Sheffield, Cambridge and UCL, and Institute of CS at Cardiff. The UK has a golden opportunity to build on our strengths in CS research that will drive innovation across a range of new opto-electronic and power electronic devices. The need arises from a new generation of functional compound semiconductor materials to capture the unique properties of oxide and chalcogenide compound semiconductors (CSs), complementing III-V compounds and silicon, and opening new application areas in optoelectronics, energy and healthcare. It is proposed that we buy the Aixtron Close Couple Showerhead (CCS) reactor that has been proven to be the reactor design of choice for GaN deposition and will be the ideal equipment to deposit high quality oxide and chalcogenide compound semiconductor materials. "The UK needs this facility, which it does not have at present. Swansea is an excellent place for it." - Prof. Sir Colin Humphreys (Cambridge). "This proposed research facility will perfectly complement the installation of ~100 production MOCVD reactors leveraged by a £375M investment by IQE Plc over 2018-2022" - Dr Wyn Meredith (CSC, Cardiff). The CCS reactor will be installed in a new building for the Centre for Integrated Semiconductor Materials (CISM) (due for completion in Q1 2021) on the Swansea University Bay Campus. Over 140 m2 of specialist materials laboratory space will be allocated to the MOCVD reactor and complementary materials and characterisation equipment from Professor Irvine's laboratory. This new laboratory will be managed by Professor Irvine's team to provide high quality oxide and chalcogenide CSs to our research partners in Swansea University, other UK universities, industrial partners and to international collaborators. This will put the UK at the forefront of new science and technology using oxide and chalcogenide CSs for applications including high efficiency photovoltaic solar cells, Light harvesting quantum wire opto-electronic devices, piezoelectric energy harvesting, high breakdown voltage power electronic devices and light emitters. This new science and technology will benefit EPSRC priorities of "21st Century Products" and "Sustainable Industries" through enabling smart new products that could be rapidly prototyped through well proven manufacturing capability for MOCVD in the UK and enabling the application of more sustainable materials and reduced materials usage. This exciting opportunity is detailed in the case for support.

II-VI族金属有机化学气相沉积（MOCVD）的历史可以追溯到IIIII-V族MOCVD，但在激光器、LED和高频器件的应用中没有III-V族半导体所经历的牵引力。新一代MOCVD设备可以更充分地挖掘II-VI族半导体的潜力，在Ga 2 O3等III-VI族和MoS 2等二维半导体的现有领域探索新的氧化物和硫属化物。目前，英国迫切需要拥有最先进的MOCVD设备，用于化合物半导体（CS），覆盖现有中心（如位于谢菲尔德、剑桥和伦敦大学学院的国家外延设施以及位于卡迪夫的CS研究所）所不覆盖的氧化物和硫属化物材料。英国有一个千载难逢的机会，可以利用我们在CS研究方面的优势，推动一系列新型光电和电力电子器件的创新。新一代功能化合物半导体材料需要捕捉氧化物和硫属化合物半导体（CS）的独特性能，补充III-V族化合物和硅，并在光电子、能源和医疗保健领域开辟新的应用领域。我们建议购买Aixtron Close Couple Showerhead（CCS）反应器，该反应器已被证明是GaN沉积反应器设计的首选，并且将是存款高质量氧化物和硫属化物化合物半导体材料的理想设备。“英国需要这个设施，它目前没有。斯旺西是一个很好的地方。“--科林·汉弗莱斯爵士教授（剑桥）。“这个拟议的研究设施将完美地补充IQE Plc在2018-2022年投资3.75亿英镑的约100个生产MOCVD反应器的安装”-Wyn Meredith博士（CSC，卡迪夫）。CCS反应堆将安装在斯旺西大学湾校区的集成半导体材料中心（CISM）（将于2021年第一季度完工）的新楼中。超过140平方米的专业材料实验室空间将分配给MOCVD反应器和补充材料和表征设备从欧文教授的实验室。这个新的实验室将由欧文教授的团队管理，为我们在斯旺西大学，其他英国大学，工业合作伙伴和国际合作者的研究合作伙伴提供高质量的氧化物和硫属化物CS。这将使英国处于使用氧化物和硫属化物CS的新科学和技术的最前沿，其应用包括高效光伏太阳能电池、光收集量子线光电器件、压电能量收集、高击穿电压电力电子器件和光发射器。这一新的科学技术将有利于EPSRC的“21世纪产品”和“可持续工业”的优先事项，通过使智能新产品，可以迅速原型通过良好的证明制造能力的MOCVD在英国和使更多的可持续材料的应用和减少材料的使用。这个令人兴奋的机会在支持案例中有详细说明。
