  • TiO2/Cu2O/CuO Multi-Nanolayers as Sensors for H2 and Volatile Organic Compounds: An Experimental and Theoretical Investigation 
    LUPAN, Oleg; SANTOS-CARBALLAL, David; ABABII, Nicolai; MAGARIU, Nicolae; HANSEN, Sandra; VAHL, Alexander; ZIMOCH, Lukas; HOPPE, Mathias; PAUPORTÉ, Thierry; GALSTYAN, Vardan; SONTEA, Victor; CHOW, Lee; FAUPEL, Franz; ADELUNG, Rainer; de LEEUW, Nora H.; COMINI, Elisabetta (American Chemical Society, 2021)
    TiO2/Cu2O/CuO multi-nanolayers highly sensitive toward volatile organic compounds (VOCs) and H2 have been grown in various thicknesses by a cost-effective and reproducible combined spray–sputtering–annealing approach. The ...
  • Toward blue emission in ZnO based LED 
    VIANA, Bruno; PAUPORTÉ, Thierry; LUPAN, Oleg; LE BAHERS, Tangui; CIOFINI, Ilaria (SPIE, 2013)
    The bandgap engineering of ZnO nanowires by doping is of great importance for tunable light emitting diode (LED) applications. We present a combined experimental and computational study of ZnO doping with Cd or Cu atoms ...
  • Ultra-sensitive and selective hydrogen nanosensor with fast response at room temperature based on a single Pd/ZnO nanowire 
    LUPAN, Oleg; POSTICA, Vasile; LABAT, Frédéric; CIOFINI, Ilaria; PAUPORTÉ, Thierry; ADELUNG, Rainer (ELSEVIER, 2018)
    In this work the gas sensing properties of nanosensors fabricated by a “bottom-up” approach in a FIB/SEM system based on a single Pd modified ZnO nanowire is investigated in detail. Synthesis, surface doping and functionalization ...
  • UV nanophotodetectors: A case study of individual Au-modified ZnO nanowires 
    LUPAN, Oleg; POSTICA, Vasile; PAUPORTÉ, Thierry; HOPPE, Mathias; ADELUNG, Rainer (ELSEVIER, 2019)
    In this work, ultraviolet (UV) nanophotodetectors based on individual gold-functionalized ZnO nanowires (Au/ZnO NWs) with different diameters and with different Au content were fabricated using a focused ion beam/scanning ...
  • Wavelength-Emission Tuning of ZnO Nanowire-Based Light-Emitting Diodes by Cu Doping: Experimental and Computational Insights 
    LUPAN, Oleg; PAUPORTÉ, Thierry; LE BAHERS, Tangui; VIANA, Bruno; CIOFINI, Ilaria (WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim, 2011)
    The band-gap engineering of doped ZnO nanowires is of the utmost importance for tunable light-emitting-diode (LED) applications. A combined experimental and density-functional theory (DFT) study of ZnO doping by copper ...
  • ZnO nanowire-based light-emitting diodes with tunable emission from near-UV to blue 
    PAUPORTÉ, Thierry; LUPAN, Oleg; VIANA, Bruno; LE BAHERS, T. (Society of Photo-Optical Instrumentation Engineers (SPIE), 2013)
    Nanowires (NWs)-based light emitting diodes (LEDs) have drawn large interest due to many advantages compared to thin film based devices. We have successfully prepared epitaxial n-ZnO(NW)/p-GaN heterojunctions using low ...
  • ZnO nanowires for tunable near-UV/blue LED 
    PAUPORTÉ, Thierry; LUPAN, Oleg; VIANA, Bruno (Society of Photo-Optical Instrumentation Engineers (SPIE), 2012)
    Nanowires (NWs)-based light emitting diodes (LEDs) have drawn large interest due to many advantages compared to thin film based devices. Markedly improved performances are expected from nanostructured active layers for ...
