Graphene Industries (GI), United Kingdom
- Manufacture of atomically thin, single crystal flakes of graphene, hexagonal boron nitride (hBN) and other 2D materials.
- Characterisation of 2D materials using optical contrast, Raman spectroscopy, AFM, SEM and electronic transport techniques.
- Transfer of 2D materials to arbitrary substrates or over apertures (to create membranes).
- Electron-beam lithography, physical vapour deposition and plasma etching to fabricate electronic devices.
Role in NANO-RF:
GI will supply large (>100,000 μm² in area) single crystal flakes of mono-, bi- and trilayer graphene to the consortium partners. Such flakes are available on a wide range of substrates:
· gold (for STM characterisation)
· quartz
· oxidised silicon (silicon resistivity can >10,000 _cm - suitable for RF measurements).
· boron nitride
· polymers (e.g. PMMA, PET)
The graphene flakes are cleaved from the very highest quality natural graphite available.
Room temperature mobilities are >10,000 cm²/VS for graphene on SiO2 and >100,000 cm²/VS for graphene on hexagonal boron nitride (hBN).
Key personnel:
Dr. Peter Blake (1981)
Peter Blake is the Managing Director of Graphene Industries and a postdoctoral researcher in the Condensed Matter Physics Group at the University of Manchester. Since 2004, he has been studying the optical & electronic properties of graphene and developing related micro-fabrication procedures. He received a PhD from the University of Manchester in 2008 (thesis title: Graphene Optics: Properties and Applications).
