    Copper oxide is a p-type metal oxide with remarkable optical, electrical, thermal and sensing properties. The oxidation of Cu2O to CuO can be performed by thermal annealing at relatively low temperatures. The present study ...
  • Pd-doped ZnO nanostructured films for multifunctional applications 
    POSTICA, Vasile; HOPPE, Mathias; ADELUNG, Rainer; PAUPORTÉ, Thierry; ABABII, Nicolai; TROFIM, Viorel; SONTEA, Victor; LUPAN, Oleg (Technical University of Moldova, 2017)
    In this work Pd-doped ZnO (ZnO:Pd) nanostructured films were deposited on pre-cleaned glass substrates via a synthesis from chemical solutions (SCS) approach from aqueous baths. The post-rowth thermal annealing, namely ...
  • Hydrogen detection by individual Pd-modified ZnO nanowire 
    LUPAN, Oleg; PAUPORTÉ, Thierry; POSTICA, Vasile; VIANA, Bruno; ADELUNG, Rainer; CHOW, Lee; TIGINYANU, Ion (Technical University of Moldova, 2017)
    In this work an individual Pd-modified ZnO nanowire (Pd/ZnO NW) was integrated into a nanosensor device using focused ion beam (FIB)/scanning electron microscopy (SEM) system. The Pd/ZnO arrays were synthesized by ...
