  • Understanding light trapping by resonant coupling to guided modes and the importance of the mode profile 

    Beck, Fiona J.; Stavrinadis, Alexandros; Lasanta, Tania; Szczepanick, John-Paul; Konstantatos, Gerasimos (OSA, 2016-01-11)
    Article
    Accés obert
    We present a simple conceptual model describing the absorption enhancement provided by diffraction gratings due to resonant coupling to guided modes in a multi-layered structure. In doing so, we provide insight into why ...
  • Highly Sensitive, Encapsulated MoS2 Photodetector with Gate Controllable Gain and Speed 

    Kufer, Dominik; Konstantatos, Gerasimos (ACS, 2015-10-26)
    Article
    Accés restringit per política de l'editorial
    Semiconducting, two-dimensional molybdenum disulfide (MoS2) is considered a promising new material for highly sensitive photodetection, because of its atomically thin profile and favorable bandgap. However, reported ...
  • Large-Area Plasmonic-Crystal−Hot-Electron-Based Photodetectors 

    García de Arquer, F. Pelayo; Mihi, Agustín; Konstantatos, Gerasimos (ACS, 2015-06-11)
    Article
    Accés obert
    In view of their exciting optoelectronic light− matter interaction properties, plasmonic−hot-electron devices have attracted significant attention during the last few years as a novel route for photodetection and ...
  • Metal-insulator-semiconductor heterostructures for plasmonic hot-carrier optoelectronics 

    García de Arquer, F. Pelayo; Konstantatos, Gerasimo (OSA, 2015-06-01)
    Article
    Accés obert
    Plasmonic hot-electron devices are attractive candidates for light-energy harvesting and photodetection applications. For solid state devices, the most compact and straightforward architecture is the metalsemiconductor Schottky ...
  • Integrated colloidal quantum dot photodetectors with color-tunable plasmonic nanofocusing lenses 

    Diedenhofen, Silke L.; Kufer, Dominik; Lasanta, Tania; Konstantatos, Gerasimos (Nature Publishin group, 2015-01-16)
    Article
    Accés obert
    High-sensitivity photodetection is at the heart of many optoelectronic applications, including spectroscopy, imaging, surveillance, remote sensing and medical diagnostics. Achieving the highest possible sensitivity for a ...
  • Molecular interfaces for plasmonic hot electron photovoltaics 

    García de Arquer, Francisco Pelayo; Mihi, Agustín; Konstantatos, Gerasimos (Royal Society of Chemistry, 2015-01-02)
    Article
    Accés obert
    The use of self-assembled monolayers (SAMs) to improve and tailor the photovoltaic performance of plasmonic hot-electron Schottky solar cells is presented. SAMs allow the simultaneous control of open-circuit voltage, ...
  • Improved electronic coupling in hybrid organic–inorganic nanocomposites employing thiol-functionalized P3HT and bismuth sulfide nanocrystals 

    Martínez, Luis; Higuchi, S.; MacLachlan, A. J.; Stavrinadis, A.; Miller, N. C.; Diedenhofen, Silke L.; Bernechea, María; Sweetnam, S.; Nelson, J.; Haque, S. A.; Tajima, K.; Konstantatos, Gerasimos (Royal Society of Chemistry, 2014-06-19)
    Article
    Accés obert
    In this study, we employ a thiol-functionalized polymer (P3HT-SH) as a leverage to tailor the nanomorphology and electronic coupling in polymer–nanocrystal composites for hybrid solar cells. The presence of the thiol ...
