题目:Are carbon nanotubes the future of Electronics ?








Since their identification by IIjima in 1991, Carbon Nanotubes (CNTs) have been touted as being one of the most promising materials systems for future electronic applications. CNTs are a unique form of carbon filament/fibre in which sheets of sp2 bonded graphite with no surface broken bonds roll up to form tubes. Single Wall Carbon Nanotubes can exhibit either semiconducting or metallic like properties whereas Multiwall Carbon Nanotubes exhibit only non-semiconducting behaviour. Both types have been investigated for their use in electronics. Their potential application in this field is based upon the several unique properties that the CNTs possess e.g they have the highest thermal conductivity, they can exhibit ballistic transport and do not suffer from electron migration. To date there have been various reports of their use in vias and interconnects, FETs, diodes, simple logic circuits, NEMS devices and various sensing applications . Also when mixed with polymers they can be used in transparent conductors, in solar cells and in photonics. However there are still several problems to overcome before their potential in most of these applications can be realised.


In this talk, the growth and characterisation of both single and multi wall CNTs is described and also some of the above applications will be discussed and a realistic appraisal of the future of CNTs in the electronics field will be provided. Although they are very unlikely, in the author’s opinion, to take over from silicon for use in the active devices such as transistors and diodes etc. in logic circuits their use in vias in next generation integrated circuits is considered as being entirely feasible as is their use in transparent conducting contacts. Another major contribution to future electronics could be in add-on applications such as bio and gas sensors integrated with silicon rather than replacing the silicon itself.




Bill Milne的简历:


Bill Milne FREng, FIET, FIMMM has been Head of Electrical Engineering at Cambridge University since 1999, Director of the Centre for Advanced Photonics and Electronics( CAPE) since 2004 and Head of the Electronic Devices and Materials group since 1996 when he was appointed to the '1944 Chair in Electrical Engineering'. He obtained his BSc from St Andrews University in Scotland in 1970 and then went on to read for a PhD in Electronic Materials at Imperial College London. He was awarded his PhD and DIC in 1973 and in 2003, a D.Eng (Honoris Causa) from University of Waterloo, Canada. He was elected as Fellow of the Royal Academy of Engineering in 2006 and was awarded the JJ Thomson medal from the IET in 2008. He is a Guest Professor at HuangZhou University in Wuhan, China and a Distinguished Visiting Professor at SEU in Nanjing, China and at NUS, Singapore. He is also a Distinguished Visisting Scholar at KyungHee University, Seoul. From 1973 until 1976 he worked at the Plessey Res Co, Caswell after which he joined Cambridge University Engineering Department as an Assistant Lecturer. On arriving in Cambridge Prof. Milne set up the Electronic Devices and Materials group, which now has 7 Staff members, approximately 30 Post doctoral research staff and Fellows and over 50 PhD students. The yearly income is of order Eu 15 Million. His research interests include large area Si and carbon based electronics, thin film materials and, most recently, MEMS and carbon nanotubes and other 1-D structures for electronic applications. He currently collaborates with various companies including Thales, Samsung, Nokia, Aixtron, and FEI and is also currently involved in 3 EU projects and several UK Government funded EPSRC projects. He has published/presented ~ 650 papers, of which ~ 150 were invited.
