| Description | Use of fountain nanopen lithography to controllably write aligned carbon nanotubes on a substrate. This allows individual nanotubes to be placed at defined positions and with defined alignment on a substrate. This provides a controlled means of fabricating devices consisting of individual nanostructures. The nanotubes were attached to electrodes and the Raman spectra and electrical properties were characterised with and without the presence of nanoplasmonic structures. Atomic force microscopy was used to manipulate individual plasmonic structures to study the Raman enhancement as a function of distance from the individual nanotube and the influence on the polarisation dependence of the Raman spectrum. This provided new insight into the fundamental properties of nanotubes and plasmonic interaction. This woe was carried out in collaboration with Prof. Aaaron Lewis (Hebrew University Jeruasalem), Prof. Stefan Maier (Imperial) and Prof. Stephanie Reich (Free University Berlin). Arrays of carbon nanotubes/nanofibres were fabricated and studied for their photonic crystal properties. The collaboration with Prof. Maier (Imperial) and Prof Kinaret (Chalmers, Sweden) provided theoretical modelling of the optical properties of the photonic crystals and collaboration with Prof. Arwin (Linkoping, Sweden) allowed detailed optical characterisation of the structures to be carried out and compared with theory. We were able to show for the first time that arrays of carbon nano fibres could be electrostatic ally actuated in order to change the lattice constants and reproducibly alter the optical properties of the array. This provides a means of producing an electronically tuneable photonic crystal that operates in the optical regime. |
| Exploitation Route | The AFM nano fountain pen deposition is being further developed by our collaborators in Israel who manufacture the AFM systems. The electrically tuneable photonics crystal nano fibre arrays are potentially useful for sensor technology or optoelectronics devices. |

| Primary Audience | Public/other audiences |
| Results and Impact | The activity sparked requests for talks to Schools and groups such as U3A. A number of requests for laboratory tours by e.g. girl guide groups were received and the tours were arranged. The display that was prepared has been used at university open days. The original exhibition at the Botanical Gardens in Edinburgh that was part of theEdinburgh International Science Festival in 2011 late toured Scotland reaching a very wide cross section of the population. |
