• Multi-scale theory and simulation of direct-gap group-IV semiconductor alloys 

  Broderick, Christopher A.; O'Halloran, Edmond J.; Dunne, Michael D.; Kirwan, Amy C.; Andreev, Aleksey D.; Schulz, Stefan; O'Reilly, Eoin P. (Institute of Electrical and Electronics Engineers (IEEE), 2020-07-13)

  Alloying of Ge with other group-IV elements - C, Sn or Pb - represents a promising route to realise direct-gap group-IV semiconductors for applications in Si-compatible devices, including light-emitting diodes and lasers, ...
• Ni, Pt, and Ti stanogermanide formation on Ge0.92Sn0.08 

  Galluccio, Emmanuele; Petkov, Nikolay; Mirabelli, Gioele; Doherty, Jessica; Lin, Shih-Va; Lu, Fang-Liang; Liu, Chee Wee; Holmes, Justin D.; Duffy, Ray (Institute of Electrical and Electronics Engineers (IEEE), 2019-04)

  The aim of this work is to provide a systematic and comparative study on the material characteristics and electrical contact performance for a germanium-tin (GeSn) alloy with a high percentage of Sn (8%). Thin metal films ...
• A simple synthesis of polymer coated gold and silver nanoparticles in water for potential use in biomedical applications 

  Rahme, Kamil; Minassian, G.; Ghanem, Esther.; Nakhl, Michel; El Hage, Rolan; Souaid, Eddy; Holmes, Justin D. (TechConnect, 2018-05)

  In this study Silver (Ag) and Gold (Au) nanoparticles (NPs) of different surface charges (positively charged, negatively charged, or nearly neutral) and sizes were obtained using ascorbic acid as a reducing agent and ...
• Dendrigraft poly-L-lysine (d-PLL) coated gold nanoparticles in water for siRNA delivery to prostate cancer cells 

  Rahme, Kamil; Minassian, G.; Ghanem, Esther; Souaid, Eddy; Guo, Jianfeng; O'Driscoll, Catriona M.; Holmes, Justin D. (TechConnect, 2018-05)

  Herein we describe a simple method for the synthesis of dendrigraft poly-L-lysine (d-PLL) coated different sizes gold nanoparticles in water (AuNPs-d-PLL) as potential to delivery vehicles of siRNA to PC-3 prostate cancer ...
• Neuromorphic-inspired behaviour in core-shell nanowire networks 

  Manning, Hugh G.; Biswas, Subhajit; Kumar, Shailja; Holmes, Justin D.; Boland, John J. (Institute of Electrical and Electronics Engineers (IEEE), 2018-07)

  Engineering smart-materials with emergent properties requires designing and characterizing systems with desirable behaviours. Neuromorphic (brain-like) architectures require plasticity, where the strength of the connections ...
