Nanotechnology

Nanotechnology deals with the science and technology associated with dimensions in the range 0.1 nm to 100 nm. We have pioneered research into low temperature grown carbon nanotubes (CNTs), right down to room temperature. This allows us to functionalise CNTs with biological materials more easily. The possibilities of growing CNT on temperature sensitive substrates such as plastic and even paper have opened up many new applications. We have also patented a method that allows us to fabricate bespoke devices using 3D manipulation of nano-materials. Devices constructed on this basis has allowed current densities in excess of 10⁹ A/cm² through CNT circuits, which is a 1000 times better than copper!

The group has extensive experience in growth and characterisation of other nanomaterials such as nanowires and rods, carbon based and other inorganic materials. The group is equipped with a state-of-the-art microscopy facility with facilities for nanoelectronic measurements with manipulation kits and a focused ion beam equipped scanning electron microscope for nanofabrication. Further, the Omicron scanning tunnelling microscope system also has the capability for ultraviolet and X-ray photoelectron spectroscopy, which are essential tools for nanoscale characterisation.
