  • Conductive films of ordered nanowire arrays
    Ziegler, Kirk J.; Polyakov, Boris; Kulkarni, Jaideep S.; Crowley, Timothy A.; Ryan, Kevin M.; Morris, Michael A.; Erts, Donats; Holmes, Justin D. (Royal Society of Chemistry, 2004)
    High-density, ordered arrays of germanium nanowires have been synthesised within the pores of mesoporous thin films (MTFs) and anodized aluminium oxide (AAO) matrices using a supercritical fluid solution-phase inclusion ...
  • Modelling of magnetisation reversal in thin films, nanodots, nanopillars and nanowires
    Lynch, Thomas Francis (University of Limerick, 2010)
    Magnetic nanostructures have attracted attention due to their possible applications in information storage and sensors. The switching time and switching field are two magnetic properties that can determine the applicability ...
  • Perpendicular growth of catalyst-free germanium nanowire arrays.
    Barrett, Christopher A.; Geaney, Hugh; Gunning, Robert D.; Laffir, Fathima R.; Ryan, Kevin M. (Royal Society of Chemistry, 2011)
    High yields of single-crystalline Ge nanowires (NWs) were synthesized through the thermal decomposition of diphenylgermane (DPG) in the vapor phase of a high boiling point organic solvent. The NWs were single crystal and ...
  • The role of defects and growth directions in the formation of periodically twinned and kinked unseeded germanium nanowires
    Geaney, Hugh; Dickinson, Calum; Weng, Weihao; Kiely, Christopher J.; Barrett, Christopher A.; Gunning, Robert D.; Ryan, Kevin M. (American Chemical Society, 2011)
    Here we show the impact of preferred growth directions and defects in the formation of complex Ge nanowire (NW) structures grown by a simple organic medium based synthesis. Various types of NWs 15 are examined including: ...
  • Spontaneous room temperature elongation of CdS and Ag2S nanorods via oriented attachment
    O'Sullivan, Catriona; Gunning, Robert D.; Sanyal, Ambarish; Barrett, Christopher A.; Geaney, Hugh; Laffir, Fathima R.; Ahmed, Shafaat; Ryan, Kevin M. (American Chemical Society, 2009)
    Spontaneous elongation from nanorod to nanowire in the presence of an amine is reported for nanocrystals of cadmium sulfide and silver sulfide (cation exchanged from CdS). Elongation occurs instantaneously where the final ...
