Research Interests

My research interests are mainly focussed in

1. Graphene based devices, doping of graphene and understanding charge transfer in the graphene - molecule system. Bilayer graphene.
2. Carbon nanotube composites for large area applications, in particular cathodes technology but also high frequency applications. See our press release on high frequency (up to 220 GHz) applications of nanotube composites.  The original paper was published in Applied Physics Letters in October 2011.  We have also be looking at high frequency characterization of low tempertaure processed metal nanoparticles and published this is ACS Applied Materials in Dec. 2012.  
3. Nanotechnology and nanomaterials in particular carbon based materials (nanotubes, graphene and DLC).  I was the Guest Editor of the Journal of Material Science:Materials in Electronics for a Special Issue on Carbon Based Electronics. 
4. The applications of low dimensional materials as field emitters.
5. The structure, electrical transport and electronic properties of nanomaterials.
6. Commercial applications of nanomaterials. Nanotechnology and Society.
