Ground-breaking production method could accelerate worldwide ‘graphene revolution'

An innovative new cheap and simple mass production technique, developed by the University of Exeter, is set to open up the global potential of the ‘wonder’ material graphene.

A team of engineers from Exeter’s Centre for Graphene Science have developed a new method for creating entire device arrays directly on the copper substrates used for the commercial manufacture of graphene. Complete and fully-functional devices can then be transferred to a substrate of choice, such as silicon, plastics or even textiles.

Professor David Wright, from Exeter’s Engineering department and one of the authors said: “The conventional way of producing devices using graphene can be time-consuming, intricate and expensive and involves many process steps including graphene growth, film transfer, lithographic patterning and metal contact deposition. Our new approach is much simpler and has the very real potential to open up the use of cheap-to-produce graphene devices for a host of important applications from gas and bio-medical sensors to touch-screen displays.”


The Exeter engineering team consisted of Dr. Arseny Alexeev, Mr. Matthew Barnes, Dr. Karthik Nagareddy and Profs Craciun and Wright, and the work was carried out as part of the EU-funded FP7 project CareRAMM.
