Quantum Efficiency Metrology of Solution-Processed Quantum Dot Optoelectronics

该奖学金是基于新成立的IDTH量子材料和技术中心（QuMAT）。学生将加入一个队列，队列方法将使来自不同背景的学生受益，从量子材料物理学到量子技术工程。这个学生将把迄今为止被认为是孤立的物理科学的各个领域联系起来，发挥国家物理实验室和卡迪夫大学在量子科学和计量学方面的优势。NPL在量子材料和计量技术方面拥有世界领先的专业知识，包括开发这些专业知识以提供技术标准应用。该奖学金将促进NPL和卡迪夫的量子效率研究（由Bo Hou博士领导的rif资助的量子效率中心）的合作，使未来在EPSRC职权范围之外的34个UKRI优先领域的赠款取得成功。量子技术器件的一个基本优点是它们的量子效率。然而，溶液处理量子器件的量子效率计量标准仍然缺失，这导致了量子器件的错误表征，从而导致了无效的量子效率结果的报告。[1-3]该研究的主要目标是生成系统的量子效率表征计量方法，以量化新兴溶液处理量子点太阳能电池和led的性能，特别侧重于为测量这些量子器件中的量子效率的标准化表征协议提供解决方案。这些新型量子材料和能量转换器件有望提供高效率、低碳足迹的能量收集和照明器件。我们希望与一名热情的博士生合作，深入了解i)界面物理，这对量子点层的生长至关重要；Ii)器件物理（外部和外部量子效率、光提取效率、多激子产生和多光子吸收），这是实现量子光子器件所必需的。在他们的博士学位结束时，他们应该产生一个测量量子点太阳能电池和led的量子效率的协议，并为溶液处理的量子点能量收集和照明设备的计量标准化提供解决方案，这也是高影响力出版物的领域。

This studentship is based on a newly formed IDTH Quantum Materials and Technology Hub (QuMAT). The student will join into a cohort and the cohort approach will benefit students who come with different backgrounds ranging from quantum materials physics to quantum technological engineering.This studentship will connect diverse fields in the physical sciences hitherto considered isolated, playing to NPL and Cardiff's strengths in quantum science and metrology. NPL has world-leading expertise in quantum materials and metrology technologies, including developing that expertise to deliver technological standard applications. This studentship will facilitate a collaboration of NPL's and Cardiff 's quantum efficiency research (RIF-funded Quantum Efficiency Hub led by Dr Bo Hou), enabling future success with grants in a range of the 34 UKRI priority areas which stretch beyond the EPSRC remit.A fundamental figure of merit of quantum technology devices is their quantum efficiency. However, a quantum efficiency metrology standard of solution-processed quantum devices is still missing, which results in quantum devices to be mischaracterised, yielding to invalid quantum efficiency results being reported.[1-3] The main goal of this studentship will be to generate systematic quantum efficiency characterisation metrologies to quantify the performance of emerging solution-processed quantum dot solar cells and LEDs, with a particular focus on providing solutions for standardising characterisation protocols for measuring the quantum efficiency in these quantum devices. These new types of quantum materials and energy conversion devices are expected to provide energy harvesting and lighting devices with high efficiency and low carbon footprints. We would like to work with an enthusiastic PhD student to develop a deep understanding of i) interface physics which is crucial for the growth of quantum dot layers; ii) device physics (external and external quantum efficiency, light extraction efficiency, multiple exciton generation and multiple photon absorption) which is essential for realising quantum photonics devices. At the end of their PhD, they should have generated a protocol for measuring the quantum efficiency of quantum dot solar cells and LEDs and contribute solutions to metrology standardisation for solution-processed quantum dot energy harvesting and lighting devices, which are also areas for high-impact publications.
