Biography
Professor Kevin M. Ryan obtained his PhD in Chemistry from University College Cork in 2002 . Following his PhD, he worked as an Enterprise Ireland postdoctoral fellow at UCC before taking up a 2 year Marie Curie Industrial host fellowship at Merck Chemicals Ltd. Southampton in their Nanotechnologies New Business division in 2003. He subsequently carried out a Marie Curie Outgoing fellowship at the University of California, Berkeley in 2005/2006 working on semiconductor nanorod synthesis and superlattice assembly. Currently his lab and group are based at the Bernal Institute, University of Limerick. www.ifnano.com for full group description
Research Interests
Keywords: Colloidal Nanocrystals, Nanorods, Nanowires, Silicon, Germanium, Cadmium Sulphide, Cadmium Selenide, Copper Indium Gallium Sulphide/selenide (CIGS), Dicopper-zinc-tin-tetrasulphide (CZTS), Nanorod Assembly, Electrophoretic Assembly, Charge based Assembly, Thin-films, Photoabsorbers, Lithium ion batteries.
The group research interests are in: [1] Colloidal Nanocrystals with particular emphasis on Semiconductor Nanorods and their device scale assembly by directed (Electric fields ) or non-directed for scaleable applications in photovoltaics. The group has pioneered routes whereby the nanorods can be assembled from solution such that each rod is Vertically Aligned and Close packed (-allowing the formation of a forest of nanoscale photo absorbers directly from solution). As the semiconductors are pot synthesized and processed from solution (-similar to an ink) they offer a low cost protocol to thin-film devices. The group has recently extended the nanorod synthesis and assembly protocols to copper indium gallium sulfide/selenide (CIGS) and dicopper-zinc-tin-tetrasulphide (CZTS). These materials are attractive for their high efficiencies in thin-film devices and CZTS in particular is viewed as an attractive long term solution for low cost photovoltaics as all the elements are in high natural abundance. Funding for this work is through a Science Foundation Ireland Principal Investigator Award and through the SFI Strategic Research Cluster in Solar Energy Conversion.
[2] Low cost solution synthesis of silicon and germanium nanowires by seeded and non-seeded strategies particularly targeted towards generating wires in high yield. We have developed a novel synthetic protocol that allows the growth of group 14 nanowires in the vapor phase of high boiling point solvents in glass ware based apparatus allowing high purity nanowires to be formed either with or without catalysts . Recently we have used indium and tin catalysts for form high density arrays of silicon and germanium wires on substrates and have extended the syntheses to metal silicide structures. Control over nanowire length for the formation of nanorods was achieved by a modification of this synthesis protocol. Investigation of nanowires of germanium as anodes for Lithium ion batteries is funded through the European Union GREENLION project with a consortium of 14 partners including large car manufactures such as SEAT and Volkswagen. The investigation of non-seeded nanowires for ICT is funded through an SFI Principal Investigator grant with industry support from Intel Ireland.
