Talk Title: Recent Developments in Hybrid and Inorganic Perovskite Halides
Speaker: Anthony K. Cheetham - Materials Research Laboratory, UCSB

Abstract: Hybrid organic-inorganic perovskites are found in a number of important families, including the lead-based halides (e.g. CH3NH3PbI3) and the formates (e.g. [(CH3)2NH2]Zn(HCOO)3) [1], as well as systems with the ReO3 structure [2]. The lead halide perovskites have attracted a great deal of attention in the last decade on account of their excellent performance as active layers in solar cells and other optoelectronic devices. I shall discuss some of our recent work which has focused on the search for lead-free hybrid and inorganic double perovskites such as (CH3NH3)2AgBiBr6 and Cs2AgSbBr6 [3]. I shall also describe some B-site vacant perovskites based on platinum [4] and ruthenium [5], as well as recent developments in the area of hybrid layered double perovskite halides [6]. Our current work on ruthenium systems is enabling us to explore the influence of chemical bonding on spit-orbit coupling effects.

Bio: Tony Cheetham is a Research Professor at the University of California, Santa Barbara, and a Distinguished Visiting Professor at the National University of Singapore. He was formerly the Goldsmiths’ Professor of Materials Science at the University of Cambridge (2007-2017) and the Treasurer and Vice-President of the Royal Society (2012-2017). He obtained his D.Phil. at Oxford in 1972 and did post-doctoral work in the Materials Physics Division at Harwell. He joined the Chemistry faculty at Oxford in 1974, and then moved to UC Santa Barbara in 1991 to become Professor in the Materials Department. From 1992-2004 he was the Director of UCSB’s Materials Research Laboratory. Cheetham was knighted by the Queen for “Services to Materials Chemistry, UK Science and Global Outreach” in January 2020
