Academics flock to McMaster-hosted Nanowire ConferenceJune 21, 2018

More than 150 delegates from around the world attended Nanowire Week 2018 in Hamilton from June 11-15, 2018.

Hosted by Ray LaPierre, Chair of McMaster's Department of Engineering Physics, Nanowire Week 2018 was five days of lively discussion on all areas of nanowire research, from growth to applications. Previously held annually for the past 10 years in Europe, this is the first year that the conference has come to North America. Nanowire Week created an open, dynamic atmosphere for discussing and debating the latest news and open questions in nanowire research. The presentations focussed on hot topics and especially on new, unpublished results. Open questions, unexpected findings and unconventional ideas were encouraged.

Semiconductor nanowires are being extensively investigated for the next generation of devices including photodetectors, photocatalysis, photovoltaics, thermoelectrics, and quantum information processing, among other applications.  Nanowires are rods or pillars of semiconductor material with one dimension (the nanowire diameter) on the order of 10 nanometers to a few hundred nanometers, and length that is much greater than the diameter (on the order of micrometers or longer).

The unique aspects of nanowires, such as large surface area, quantum confinement, and effective strain relaxation, promise improved performance compared to conventional bulk or thin film technology. All nanowire researchers were invited to contribute their original research results on experimental, theoretical and technological aspects of semiconductor nanowires. Topics covered included nanowire synthesis: physical and chemical growth methods; nanowire growth modeling; advanced microscopies and related spectroscopies applied to nanowires; optical, electrical, thermal and mechanical properties of nanowires; quantum behavior of nanowires; sensors and actuators: chemical, biological, optical, microfluidic; electronic and optoelectronic nanowire devices: light emitters, transistors, solid-state lasers, plasmonics; and energy conversion and storage: photovoltaic, thermoelectric, electrochemical, batteries, and supercapacitors.

There were 155 delegates from around the world including  Australia, Iceland, Latvia, United Kingdom, Brazil, Russia, Israel, Austria, Netherlands, Poland, China, Czech Republic, Finland, Norway, Italy, Denmark, Switzerland, Japan, Germany, Sweden, USA, France and Canada.
