Realising the Commercial Impact of Graphene in Electronic Devices

Thursday, 19 June 2025

It is now two decades since the isolation of graphene by Geim and Novoselev at the University of Manchester. The initial euphoria resulting from the confirmation of theoretical predictions of unique electronic band structures for graphene as a truly 2D material, created a steady parade of structures and esoteric devices with superlative performance that have continually whetted the appetite for graphene to be incorporated in a myriad of different electronic, photonic and sensing products. The realisation of these commercially viable products in this electronics space has, however, been conspicuously slow to materialise. In many ways the simplicity of the methodology used in this original isolation has perpetuated a general mode of film transfer where demonstration vehicles are relatively easy to demonstrate, yet, often find considerable challenges when considering scale-up into commercial manufacturing.

To directly address this scale-up challenge, Paragraf has pursued growth and subsequent processing of graphene films by what could be considered industry standard methods. Films are grown, remain and are processed on semiconductor grade substrates using commercially available wafer fab processes. Through this strategy, Paragraf is not only able to demonstrate the ability to exploit the esoteric properties afforded by 2D materials, but is also addressing standard semiconductor industry process approaches to delivering stable, reliable graphene-based products at volume. What we present here is an overview and use-cases for the methodologies used within Paragraf aimed at growth of 2D films of exceptional quality that are subsequently processed to retain and deliver properties required by their final products.
