We invite you to join Professor Aravind Vijayaraghavan as he delivers his inaugural lecture, titled 'Graphene hammocks – novel devices with suspended atomically-thin materials'.
'In my inaugural lecture, I will talk about true 2-dimensional materials, graphene sheets that are suspended and free from substrate influence, and form the thinnest hammocks ever made, with unique properties and exciting applications. I will chart the course of this research, starting from my early days as a PhD student working on carbon nanotube (CNT) electronic devices and the journey that took me to all corners of the world and has led me to novel devices with suspended atomically-thin material in Manchester. My early research with CNT devices in the USA and Japan revealed how environmental interactions significantly affect the device performance. Simultaneously, I also encountered the significant challenge of large-scale fabrication of such nano-scale devices.
My post-doctoral research in Germany was focussed on solving this challenge of scaling up CNT device fabrication, which incidentally gave me my first chance to develop devices of suspended CNTs. This was followed by a brief stint at MIT where I immersed myself in all things graphene, before arriving in Manchester in the autumn of 2010, a month before the Nobel Prize for graphene was announced. At Manchester, I combined all my previous experience and expertise to focus, among other things, on developing novel suspended graphene devices and demonstrating their scalable fabrication. I will talk about various kinds of such devices I have demonstrated, including pressure and touch sensors, electrochemical sensors, opto-electronic devices, and more. Finally, I will take this opportunity to talk about my efforts and experience in trying to take many of the technologies I have developed from lab to market, the trials, tribulations and triumphs.'
