    • Mechanical Robustness of Graphene on Flexible Transparent Substrates. 

      Kang, Moon Hyo; Prieto López, LO; Chen, B; Teo, K; Williams, JA; Milne, WI; Cole, Matthew Thomas (American Chemical Society, 2016-08-31)
      This study reports on a facile and widely applicable method of transferring chemical vapor deposited (CVD) graphene uniformly onto optically transparent and mechanically flexible substrates using commercially available, ...
    • Microwave Absorption and Radiation from Large-area Multilayer CVD Graphene 

      Wu, Bian; Tuncer, Hatice M; Katsounaros, Anestis; Wu, Weiping; Cole, Matthew Thomas; Ying, Kai; Zhang, Lianhong et al. (Elsevier, 2015-06-09)
      Here we experimentally study the microwave absorption and near-field radiation behaviour of monolayer and few-layer, large-area CVD graphene in the C and X bands. Artificial stacking of CVD graphene reduces the sheet ...
    • Optoelectronic Temporal Stability of Metal Chloride-Doped CVD Graphene 

      Kang, Moon Hyo; Milne, William Ireland; Cole, Matthew Thomas (Wiley, 2016-05-11)
      In this study, we report on the development of a doping scheme for large-area chemical vapour deposited graphene transferred to optically transparent and mechanically flexible polymer supports. The temporal stability of ...
    • Parametrically Optimized Carbon Nanotube-Coated Cold Cathode Spindt Arrays 

      Yuan, X; Cole, Matthew Thomas; Zhang, Y; Wu, J; Milne, WI; Yan, Y (MDPI, 2017-01-12)
      Here, we investigate, through parametrically optimized macroscale simulations, the field electron emission from arrays of carbon nanotube (CNT)-coated Spindts towards the development of an emerging class of novel vacuum ...
    • Suppressed Hysteretic Field Emission from Polymer Encapsulated Silver Nanowires 

      Cole, Matthew Thomas; Coskun, S; Parmee, Richard; Hiralal, P; Cepek, C; Robertson, AW; Li, C et al. (IEEE, 2017-01-01)
      Suppression of the hysteretic electron emission in one-dimensional nanomaterial-based electron sources remains a critical barrier preventing their wide scale adoption in various vacuum electronics applications. Here, we ...
    • Theoretical Research on a Multibeam-Modulated Electron Gun Based on Carbon Nanotube Cold Cathodes 

      Yuan, Xuesong; Wang, Bin; Cole, Matthew Thomas; Zhang, Yu; Deng, Shaozhi; Milne, William I; Yan, Yang (IEEE, 2016-05-20)
      Multi-beam modulation in a carbon nanotube (CNT) cold cathode electron gun is herein investigated in order to develop miniaturized and fully integrated vacuum electron devices. By exposing the electron source to a ...
    • Ultra-broadband polarisers based on metastable free-standing aligned carbon nanotube membranes 

      Cole, Matthew Thomas; Doherty, Matthew; Parmee, Richard; Dawson, Paul; Milne, William Ireland (2014-07-24)
      A carbon nanotube free-standing linearly dichroic polariser is developed using solid-state extrusion. Membrane cohesion is experimentally and numerically demonstrated to derive from inter-tube van der Waals interactions ...
