Towards a Universal Lab-on-Chip Sensor from a Single Graphene Sheet: from Photodetection to Biosensing

Graphene’s exceptional environmental sensitivity in combination with unique optical, electronic and chemical properties suggest a wide range of next-generation smart sensor applications from photodetection to biosensing. This post-doctoral research project aims to identify, investigate and overcome the key bottlenecks towards realisation of a Universal graphene sensor. This significant nanoengineering challenge will require a combination of device design, nanofabrication, selective functionalisation and passivation. The development of novel nanoengineering methods and demonstration of multiple coexisting and parallel sensor functionalities can pave the way for the next generation of smart sensors and lab-on-chip technologies.

In this seminar, the project plan will be introduced with a report on initial progress. A brief overview of wider interests will also be discussed, including; microscopy and spectroscopy methods for nanodevices and material analysis; dielectric nanolayers and nanocapacitors; epitaxial graphene grown on silicon carbide; and quantum Hall devices for resistance metrology. The aim of this seminar is to introduce the post-doctoral researcher and their research project to the Institute of Solid State Physics in the hope of fruitful discussions, sharing expertise and future collaboration opportunities.

Dr. Tom Yager graduated from Royal Holloway, University of London, UK in 2009 with an MSci in Physics. In 2016, he completed his doctorate in Nanoscience at Chalmers University of Technology, Göteborg, Sweden. Here, he worked at the Quantum Device Physics laboratory and MC2 cleanroom, within the research group of Prof. Sergey Kubatkin, developing epitaxial graphene technology for quantum metrology. After completing his PhD, Tom joined the Institute of Biomedical Engineering and Nanotechnologies, RTU, Latvia in the group of Prof. Jurijs Dehtjars, employing spectroscopic analysis of silicon nitride dielectric nanolayers for nanocapacitors. Tom is currently a Post-Doctoral researcher working at the Laboratory of Prototyping, ISSP in the group of Dr. Gatis Mozoļevskis.
