• Tailoring asymmetric discharge-charge rates and capacity limits to extend Li-O2 battery cycle life 

  Geaney, Hugh; O'Dwyer, Colm (John Wiley & Sons, Inc., 2017-01-27)

  Widespread issues with the fundamental operation and stability of Li-O2 cells impact cycle life and efficiency. While the community continues to research ways of mitigating side reactions and improving stability to realize ...
• Low temperature germanium to silicon direct wafer bonding using free radical exposure 

  Byun, Ki Yeol; Ferain, Isabelle; Fleming, Peter; Morris, Michael A.; Goorsky, Mark; Colinge, Cindy (AIP Publishing, 2010)

  A low temperature germanium (Ge) to silicon (Si) wafer bonding method was demonstrated by in situ radical activation bonding in vacuum. In order to gain further insight into the bonding mechanism, the Ge surface chemistry ...
• Fabrication of p-type porous GaN on silicon and epitaxial GaN 

  Bilousov, O. V.; Geaney, Hugh; Carvajal, J. J.; Zubialevich, Vitaly Z.; Parbrook, Peter J.; Giguere, A.; Drouin, D.; Diaz, F.; Aguilo, M.; O'Dwyer, Colm (AIP Publishing, 2013)

  Porous GaN layers are grown on silicon from gold or platinum catalyst seed layers, and self-catalyzed on epitaxial GaN films on sapphire. Using a Mg-based precursor, we demonstrate p-type doping of the porous GaN. Electrical ...
• Rapid, low temperature synthesis of germanium nanowires from oligosilylgermane precursors 

  Meshgi, Mohammad A.; Biswas, Subhajit; McNulty, David; O'Dwyer, Colm; Verni, Giuseppe A.; O'Connell, John; Davitt, Fionán; Letofsky-Papst, Ilse; Poelt, Peter; Holmes, Justin D.; Marschner, Christoph (American Chemical Society, 2017-05-08)

  New oligosilylgermane compounds with weak Ge–H bonds have been used as precursors for the rapid synthesis of germanium (Ge) nanowires in high yields (>80%), via a solution–liquid–solid (SLS) mechanism, using indium (In) ...
• Gate-controlled heat generation in ZnO nanowire FETs 

  Pescaglini, Andrea; Biswas, Subhajit; Cammi, Davide; Ronning, Carsten; Holmes, Justin D.; Iacopino, Daniela (Royal Society of Chemistry, 2017-05-02)

  Nanoscale heating production using nanowires has been shown to be particularly attractive for a number of applications including nanostructure growth, localized doping, transparent heating and sensing. However, all ...
