  • 2006- Present: Senior Lecturer (Department of Materials, Imperial college, London)

Dr Riley joined the Department of Materials at Imperial College London in October 2006. He moved to Imperial from the School of Chemistry at the University of Bristol where, for almost a decade, he had run a successful research group investigating the formation and assembly of nanoparticles on electrode surfaces, a bottom-up approach to nanoparticle modified electrodes. Prior to his appointment as a lecturer at Bristol he worked as a PDRA in the group of Professor Laurie Peter at the University of Bath. Here he undertook investigations of the formation and characterisation of porous silicon, a nanoparticle modified electrode prepared by a top-down approach. Dr Riley was awarded a MA and DPhil from Oriel College, University of Oxford; his doctoral research activity was supervised by Professor Richard Compton.

Underpinning the majority of my research is electrochemistry and in particular the photoelectrochemistry of semiconductors. Over the past decade my research activity has primarily focused on the use of electrochemistry to fabricate and characetrise nanomaterials. Templated electrodeposition, in both track etched polyer membranes and anodic alumina membranes, have allowed us to prepare nanorods of various materials. Electron microscopy (TEM and SEM) and XRD have been employed to characetrise the as-prepared materials. Use of the as-prepared materials in solar energy harvesting, photocatalysis and display applications is on-going. We also have a strong activity in the area of semiconductor Q-dot modified electrodes. II-VI Q-dots are fabricated in-house and deposited onto electrodes; using self-assembly, chemical anchoring and electrophoretic deposition. The as-prepared electrodes are characterised using photoelectrochemistry. The potential of Q-dot modified electrodes in solar cell applications is under consideration.

This image shows a porous copper sample prepared by growing copper in a sea urchin shell. The triply periodic minimal surface of the sea urchin means that the sample has exceptional mechanical strength for its density.

CdSe quatum dot particles, each suspension contains monodisperse (size distribution <5%) particles. The suspensions displayed are in the size range 2 nm to 5 nm. The as-prepared particles are all CdSe with the same crystal structure. Owing to quantum confinement of charge carriers by the crystal lattice the different sized dots emit at different wavelengths.
