- Research interests
Graham's research is focused on the chemistry of nanoscale interfaces. Currently, three themes are of special interest:
- nanophotonics, including nanofabrication and plasmonics
- biologically-inspired design, in particular the construction of photonic materials inspired by photosynthetic systems
- molecular interactions at nanometre scale interfaces, including fundamental investigations of the thermodynamics and mechanics of sliding contacts between molecules (nanotribology)
In strong light-matter coupling, an ensemble of excitons (molecular excited states) is hybridised with a confined optical mode (localised surface plasmon resonance) to create new states called plexcitons that combine the properties of light and matter. Our goal is to combine strong light-matter coupling with biologically-inspired design principles, to create new materials for applications in technologies such as solar energy capture and photocatalysis.
In our 'molecular photonic breadboards', minimal units - synthetic antenna complexes - are designed from scratch to organise molecular components precisely in space and assembled to form nanostructured films, with the aim of controlling excitation transfer from the nm to the cm scale. This work builds on our core expertise in making and characterising molecular thin films, including self-assembled monolayers (ordered molecular films formed by spontaneous adsorption onto a solid surface) and polymer brushes (polymers grown from surface-bound initiator molecules). We have developed a suite of techniques for manipulating surface chemistry at the nanometre scale, including nanophotonic methods based upon near-field photolithography and interferometric methods. We use powerful analytical methods, including atomic force microscopy, X-ray photoelectron spectroscopy and secondary ion mass spectrometry, to characterise the chemistry of molecular films.
Using scanning probe microscopy, we measure noncovalent interactions between organic molecules at nanoscale interfaces, and we measure nanoscale sliding forces (friction) to explore the thermodynamics of molecular interfaces. Using these quantitative measurements we explore the molecular origins of friction and adhesion in a diversity of applications, including hair-care, laundry detergents and lubrication systems. Our goal is to use nanoscience to discover how to design sustainable alternatives to the active components in these important every-day products.
