报告摘要
Perovskites are the wonder compounds of materials science, with examples of magnets, ferroelectrics, superconductors, ion conductors, and more recently, high-efficiency solar cells. This seminar will address the physical properties that make metal halide perovskites unique. After a decade of intensive research, there has been a number of breakthroughs in understanding, but challenges and opportunities remain. To understand the success of methylammonium lead iodide photovoltaics, we have applied materials theory and simulation across multiple length scales. These organic-inorganic semiconductors satisfy the optoelectronic criteria for an active photovoltaic layer, i.e. spectral response in the visible range combined with light electron and hole effective masses. In addition, these systems are structurally and compositionally flexible with the ability to alloy on each of the lattice sites. I will discuss issues ranging from disorder associated with molecular vibrations and rotations within the inorganic network, to the role of relativistic effects, and spontaneous electric polarisation with signatures of ferroelectric and ferroelastic responses.报告人介绍
Aron Walsh is Professor of Materials Design at Imperial College London and an Underwood Distinguished Visiting Professor at Yonsei University. He was awarded his PhD in Chemistry from Trinity College Dublin (Ireland), completed a postdoctoral position at the National Renewable Energy Laboratory (USA), and held a Marie Curie fellowship at University College London (UK). He began his independent research career at the University of Bath where he held a Royal Society University Research Fellowship. His research combines technique development and applications at the interface between solid-state chemistry and physics. He was awarded the EU-40 prize from the Materials Research Society for his work on the theory of solar energy materials, as well as the 2019 Corday-Morgan Prize for his contributions to computational chemistry. He is featured in the Clarivate Highly Cited Researchers List and is Associate Editor for Journal of the American Chemical Society.
“半语-益言”系列讲座简介
《半导体学报》是中国科学院主管、中国电子学会和中国科学院半导体研究所主办的学术刊物，1980年创刊，首任主编是王守武院士，黄昆先生撰写了创刊号首篇论文，现任主编是中科院副院长、国科大校长李树深院士。2009年改为全英文月刊Journal of Semiconductors（简称JOS），同年开始与IOP英国物理学会出版社合作向全球发行。2019年入选科协”中国科技期刊卓越行动计划”。2020年，JOS被EI收录。
近年来，《半导体学报》进行了一系列改革，在创刊四十年之际，2020年启动实施 “中国半导体年度十大研究进展”的推荐和评选工作；创建了JOSarXiv预发布平台，JOSarXiv致力于为国内外半导体领域科研人员提供中英文科技论文免费发布和获取的平台；针对半导体领域热点研究方向，组织多期系列专刊进行系统性、专业性介绍，为半导体领域科研工作者学术研究提供参考。经过一系列改革措施，《半导体学报》论文质量、行业影响力和论文引用率稳步提升，得到了国内外科研人员的大力支持和认可。
半导体集成电路和光电子芯片产业作为信息技术产业的核心，是支撑经济社会发展和保障国家安全的战略性、基础性和先导性产业。近年来，随着国内外形势的快速变化发展，无论是半导体科研人员还是普通民众都对半导体芯片技术与产业的发展非常关注，期望我国能够尽快构建安全、自主、可控的半导体芯片研发与产业生态体系，早日摆脱受制于人的被动局面。
《半导体学报》举办"半语-益言"系列讲座，希望通过系列讲座普及半导体科学基础知识和前沿发展动态（即“半语”），让更多人了解半导体的内涵与外延并从中获得有用的知识（即“益言”），共同推动我国半导体科技与产业的发展。
