    • 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 ...
