Structure-functional property-device performance relationships in electronic and energy materials and devices

这项提案寻求资金支持一个研究项目，该项目受到联合国可持续发展目标7(全民负担得起的清洁能源)、11(可持续城市和社区)和12(负责任的消费和生产)的启发，旨在减轻电子产品及其动力元件对环境的影响。2019年，电气和电子设备废物(WEEE或电子废物)在全球范围内占53.6公吨，人均7.3公斤。自2014年以来，电子垃圾的数量增加了9.2公吨，联合国大学预计到2030年将增长到74.7公吨。有计划的报废和缺乏对环境无害的寿命终结情景导致了这种急剧增长。拟议研究计划背后的愿景是在电子和电化学材料和器件中建立扩展的结构-功能特性-器件性能关系，以同时优化它们的技术和环境性能。该计划解决了以下关键挑战：(I)天然(生物来源)有机电子材料(基于具有单碳键和双碳键交替的分子和聚合物)薄膜中的分子组装和拆解，以控制设备运行期间的稳定性和可靠性，以及在设备寿命结束时的有效生物降解；(Ii)对于具有结构层次(超结构)的天然材料，在不同的长度尺度上探测电荷转移和质子和电子传输，以揭示结构层次和传输之间的相互作用；以及(Iii)锂离子电池(LIBS)插层金属氧化物电极材料中的电子-离子(离子)混合输运，以深入了解LiB电极在不同荷电状态下的电子行为，以便在LIBS中最佳使用。我的实验室提供的尖端设备，例如用于在空间上解析所研究材料的化学、地形和电荷转移及传输性质的多探针光谱-形态-电化学系统，以及蒙特利尔理工学院/蒙特利尔大学校园提供的基础设施，将有助于这项研究的成功。在这个拟议的项目中，我计划培训五名博士生，他们是从才华横溢、多元化的招聘库中挑选出来的，其中包括寻求股权的团体的成员。我们的计划将在物理学、物理化学、分子科学和设备工程之间创造新的跨学科知识，包括基础知识和应用知识，并将在其技术和知识进步中整合，使所有加拿大人平等地获得社会和经济利益。拟议的计划将培训HQP，他们能够根据当前和未来的工业需求做出受过教育、负责任和符合道德的决策，拥有与绿色技术、生物医学、能源和先进制造业相关的技能。

This proposal seeks funding to support a research program that, inspired by the United Nations Sustainability Development Goals 7 (Affordable and Clean Energy for All), 11 (Sustainable Cities and Communities) and 12 (Responsible Consumption and Production), aims at alleviating the environmental impact of electronics and their powering elements. In 2019, electrical and electronic equipment waste (WEEE or e-waste) represented 53.6 Mt at the global level, an average of 7.3 kg per capita. The amount of e-waste grew by 9.2 Mt since 2014 and the United Nations (UN) University projects it to grow to 74.7 Mt by 2030. Planned obsolescence and the lack of environmentally benign end-of-life scenarios cause such dramatic increase. The vision behind the proposed research program is to build extended structure-functional property-device performance relationships in electronic and electrochemical materials & devices to simultaneously optimize their technical and environmental performance. The program addresses key challenges in: (i) molecular assembly and disassembly in films of natural (biosourced) organic electronic materials (based on molecules and polymers that feature an alternation of single and double carbon-carbon bonds), to control device stability and reliability during operation as well as efficient biodegradation at the device end-of-life; (ii) charge transfer and protonic & electronic transport, probed at different length scales, for natural materials featuring structural hierarchy (superstructure), to shed light on the interplay between structural hierarchy and transport; and (iii) mixed electronic-ionic (iontronic) transport in intercalation metal oxide electrode materials for lithium-ion batteries (LIBs), to gain insight on the electronic behavior of LIB electrodes at different states of charge, for their optimal use in LIBs. Cutting edge equipment available in my laboratory, e.g. a multiprobe spectroscopy-morphology-electrochemical system to spatially resolve chemical, topographical and charge transfer & transport properties of the materials under investigation, together with infrastructure available on Polytechnique Montreal/University of Montreal Campus, will contribute to the success of the research. During this proposed program, I plan to train five PhD students, selected from a talented and diverse recruiting pool, including members of equity-seeking groups. Our program will create new interdisciplinary knowledge, both fundamental and applied, at the interface between physics, physical chemistry, molecular sciences and device engineering and will integrate both in its technological and knowledge advances equitable access to the societal and economic benefits to all Canadians. The proposed program will train HQPs who can make educated, responsible and ethical decisions on present and future industrial needs, with skills relevant for the greentech, biomedical, energy and advanced manufacturing sectors.
