  • Emergent properties of an organic semiconductor driven by its molecular chirality 

    Yang, Ying; Rice, Beth; Shi, Xingyuan; Brandt, Jochen R; Correa da Costa, Rosenildo; Hedley, Gordon J; Smilgies, Detlef-M; Frost, Jarvist M; Samuel, Ifor D W; Otero-de-la-Roza, Alberto; Johnson, Erin R; Jelfs, Kim E; Nelson, Jenny; Campbell, Alasdair J; Fuchter, Matthew J (2017-08-22) - Journal article
    Chiral molecules exist as pairs of non-superimposable mirror images; a fundamental symmetry property vastly underexplored in organic electronic devices. Here, we show that organic field-effect transistors (OFETs) made from ...
  • Laser chemosensor with rapid responsivity and inherent memory based on a polymer of intrinsic microporosity 

    Wang, Yue; McKeown, Neil B.; Msayib, Kadhum J.; Turnbull, Graham A.; Samuel, Ifor D. W. (2011-03) - Journal article
    This work explores the use of a polymer of intrinsic microporosity (PIM-1) as the active layer within a laser sensor to detect nitroaromatic-based explosive vapors. We show successful detection of dinitrobenzene (DNB) by ...
  • LED pumped polymer laser sensor for explosives 

    Wang, Y.; Morawska, P.O.; Kanibolotsky, A.L.; Skabara, P.J.; Turnbull, G.A.; Samuel, I.D.W. (2013-11) - Journal article
    A very compact explosive vapor sensor is demonstrated based on a distributed feedback polymer laser pumped by a commercial InGaN light-emitting diode. The laser shows a two-stage turn on of the laser emission, for pulsed ...
  • Novel fast color-converter for visible light communication using a blend of conjugated polymers 

    Sajjad, M.T.; Manousiadis, P.P.; Chun, H.; Vithanage, D.A.; Rajbhandari, S.; Kanibolotsky, A.L.; Faulkner, G.; Obrien, D.; Skabara, P.J.; Samuel, I.D.W.; Turnbull, G.A. (2015-02-18) - Journal article
    Visible Light Communications (VLC) is a promising new technology which could offer higher data transmission rates than existing broadband RF/microwave wireless technologies. In this paper, we show that a blend of semiconducting ...
  • One- and two-photon pumped organic semiconductor lasers 

    Tsiminis, Georgios (University of St Andrews, 2010) - Thesis
    This thesis describes a number of studies on organic semiconductors focused around using them as gain media for lasers. The photophysical properties of organic semiconductors are studied using a wide range of ...
