Sir Richard Henry Friend (born 18 January 1953) is a British physicist who was theCavendish Professor of Physics at theUniversity of Cambridge from 1995 until 2020[7] and is Tan Chin Tuan Centennial Professor at theNational University of Singapore. Friend's research concerns thephysics and engineering ofcarbon-basedsemiconductors.[8] He also serves as Chairman of the Scientific Advisory Board of the National Research Foundation (NRF) of Singapore.[9]
Friend was educated atRugby School andTrinity College, Cambridge,[6] gaining a PhD in 1979 under the supervision of Abe Yoffe.[10]
Friend's research has been applied to development ofpolymerfield effect transistors,light-emitting diodes,photovoltaic diodes, optically pumped lasing and directly printed polymer transistors. He pioneered the study of organic polymers and the electronic properties ofmolecular semiconductors. He is one of the principal investigators in the new Cambridge-based Interdisciplinary Research Collaboration (IRC) onnanotechnology and co-founder ofCambridge Display Technology (CDT) andPlastic Logic. Friend has co-authored over 1,000 publications.[11][12]
In March 2003 Friend won theIEE'sFaraday Medal. He was knighted for "services to physics" in the2003 Birthday Honours.
Friend received an Honorary Doctorate fromHeriot-Watt University in 2006[13]
In 2009, Friend was awarded theInstitute of PhysicsKatharine Burr Blodgett Medal and Prize with Dr David Ffye.[14]
In 2010, Friend was elected as one of the three laureates ofMillennium Technology Prize for the development of plastic electronics.[15]
In 2011 he was awarded theHarvey Prize of the Technion in Israel.[16] He is a fellow ofSt John's College, Cambridge. He was elected aFellow of the Royal Academy of Engineering (FREng) in 2002.
In 2013, Friend was elected a member of theNational Academy of Engineering for contributions to science, engineering, and commercialization of organic polymer semiconductor devices.
His nomination for the Royal Society reads:
Distinguished for his experimental study of the electronic properties of novel materials, principally organic materials, both semiconductors and metals, and inorganic materials with "low-dimensional"electronic structure, including layer structuretransition metaldichalcogenides andcuprate superconductors. He established the pressure/temperaturephase diagrams for transition metal dichalcogenides, showing conditions forCDW (Charge Density Wave) phases and superconducting phases inTaS2, band crossing transition inTiS2 intercalation of transition metal dichalcogenides with variousLewis bases (alkali metals,amines), and use of controlled charge transfer to the host layer to fine-tune electronic structure to establish conditions for CDWsuperlattice formation, and mechanisms for charge transport.He has made a major contribution to understanding the conditions for metallic, superconducting, magnetic and insulatingground states inorganic charge transfer salts. Established the pressure/temperature phase diagram for the incommensurate and commensurate Charge Density Wave phases ofTTF-TCNQ. He made the first observations ofde Haas van Alphen oscillations inmagnetic susceptibility in anorganic metal. He and his group has developed polymer processing techniques for conjugated polymers, and demonstratednon-linearelectronic excitations through electrical and optical measurements. First construction ofMOSFET (Metal Insulator Semiconductor Field Effect Transistor) withpolyacetylene as active semiconductor, and demonstration of novel mechanism of operation, with novel behaviour and made the first construction of efficient, large area, polymeric semi-conductorLED's (Light Emitting Diodes), based onpolyphenylene-vinylene.[17]
Friend lives in Cambridge with his wife, Carol Anne Maxwell (née Beales) with whom he has two daughters.[6]
