  • Al2O3/ZnO Heterostructure-Based Sensors for Volatile Organic Compounds in Safety Applications 
    LUPAN, Oleg; SANTOS-CARBALLAL, David; MAGARIU, Nicolae; MISHRA, Abhishek Kumar; ABABII, Nicolai; KRÜGER, Helge; WOLFF, Niklas; VAHL, Alexander; BODDULURI, Mani Teja; KOHLMANN, Niklas; KIENLE, Lorenz; ADELUNG, Rainer; LEEUW, Nora H. de; HANSEN, Sandra (American Chemical Society, 2022)
    In this work, we demonstrate the sensing properties toward the most common VOCs of columnar Al2O3/ZnO heterolayer-based sensors. We have also developed an approach to tune the sensor selectivity by changing the thickness ...
  • Comparison of Thermal Annealing versus Hydrothermal Treatment Effects on the Detection Performances of ZnO Nanowires 
    LUPAN, Oleg; MAGARIU, Nicolae; KHALEDIALIDUSTI, Rasoul; MISHRA, Abhishek Kumar; HANSEN, Sandra; KRÜGER, Helge; POSTICA, Vasile; HEINRICH, Helge; VIANA, Bruno; ONO, Luis Katsuya; CUENYA, Beatriz Roldan; CHOW, Lee; ADELUNG, Rainer; PAUPORTÉ, Thierry (American Chemical Society, 2021)
    A comparative investigation of the post-electroplating treatment influence on the gas detecting performances of single ZnO nanorod/nanowire (NR/NW), as grown by electrochemical deposition (ECD) and integrated into nanosensor ...
  • Heterostructure-based devices with enhanced humidity stability for H2 gas sensing applications in breath tests and portable batteries 
    LUPAN, Oleg; ABABII, Nicolai; MISHRA, Abhishek Kumar; BODDULURI, Mani Teja; MAGARIU, Nicolae; Alexander VAHL, Alexander VAHL; KRÜGER, Helge; WAGNER, Bernhard; FAUPEL, Franz; ADELUNG, Rainer; LEEUW, Nora H. de; HANSEN, Sandra (Elsevier, 2021)
    Semiconducting metal oxide - based gas sensors exhibit outstanding sensitivity, although humidity in the analyte typically hampers precise measurements. In this work it was shown that a 5−6 nm thin Al2O3 nano-layer is ...
  • Improved Long-Term Stability and Reduced Humidity Effect in Gas Sensing: SiO2 Ultra-Thin Layered ZnO Columnar Films 
    POSTICA, Vasile; LUPAN, Oleg; GAPEEVA, Anna; HANSEN, Luka; KHALEDIALIDUSTI, Rasoul; MISHRA, Abhishek Kumar; DREWES, Jonas; KERSTEN, Holger; FAUPEL, Franz; ADELUNG, Rainer; HANSEN, Sandra (John Wiley & Sons, Inc., 2021)
    The undoped and metal-doped zinc oxide columnar films (ZnO:Sn, ZnO:Fe, ZnO:Ag, and ZnO:Cu) are covered with an ultra-thin layer of SiO2 (10–20 nm). The electrical, UV, and volatile organic compounds (VOCs) sensing properties ...
  • Multifunctional Materials: A Case Study of the Effects of Metal Doping on ZnO Tetrapods with Bismuth and Tin Oxides 
    POSTICA, Vasile; GRÖTTRUP, Jorit; ADELUNG, Rainer; LUPAN, Oleg; MISHRA, Abhishek Kumar; LEEUW, Nora H. de; ABABII, Nicolai; CARREIRA, José F. C.; RODRIGUES, Joana; SEDRINE, Nebiha Ben; CORREIA, Maria Rosário; MONTEIRO, Teresa; SONTEA, Victor; MISHRA, Yogendra Kumar (WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim, 2017)
    Hybrid metal oxide nano- and microstructures exhibit novel properties, which make them promising candidates for a wide range of applications, including gas sensing. In this work, the characteristics of the hybrid ZnOBi2O3 ...
  • Pd-Functionalized ZnO:Eu Columnar Films for Room-Temperature Hydrogen Gas Sensing: A Combined Experimental and Computational Approach 
    LUPAN, Cristian; KHALEDIALIDUSTI, Rasoul; MISHRA, Abhishek Kumar; POSTICA, Vasile; TERASA, Maik-Ivo; MAGARIU, Nicolae; PAUPORTÉ, Thierry; VIANA, Bruno; DREWES, Jonas; VAHL, Alexander; FAUPEL, Franz; ADELUNG, Rainer (American Chemical Society, 2020)
    Reducing the operating temperature to room temperature is a serious obstacle on long-life sensitivity with long-term stability performances of gas sensors based on semiconducting oxides, and this should be overcome by new ...
  • Single CuO/Cu2O/Cu Microwire Covered by a Nanowire Network as a Gas Sensor for the Detection of Battery Hazards 
    LUPAN, Oleg; ABABII, Nicolai; MISHRA, Abhishek Kumar; GRONENBERG, Ole; VAHL, Alexander; SCHÜRMANN, Ulrich; DUPPEL, Viola; KRÜGER, Helge; CHOW, Lee; KIENLE, Lorenz; FAUPEL, Franz; ADELUNG, Rainer; LEEUW, Nora H. de; HANSEN, Sandra (American Chemical Society, 2020)
    In this study, a strategy to prepare CuO/Cu2O/Cu microwires that are fully covered by a nanowire (NW) network using a simple thermal-oxidation process is developed. The CuO/Cu2O/Cu microwires are fixed on Au/Cr pads with ...
