  • Annealing effect on UV detection properties of ZnO:Al structures 
    NAGPAL, Rajat; CHIRIAC, Maxim; SEREACOV, Alexandr; BIRNAZ, Adrian; ABABII, Nicolai; LUPAN, Cristian; BUZDUGAN, Artur; SANDU, Iulia; SIEBERT, Leonard; PAUPORTÉ, Thierry; LUPAN, Oleg (Technical University of Moldova, 2023)
    The aim of this study was to develop low-powered, highly selective UV sensor to continuously monitor personalized UV exposure as well as to study annealing effect on UV detection properties of the sensors. ZnO:Al structures ...
  • Enhancement in UV sensing properties of ZnO:Ag nanostructured films by surface functionalization with noble metalic and bimetallic nanoparticles 
    POSTICA, Vasile; VAHL, Alexander; MAGARIU, Nicolae; TERASA, Maik-Ivo; HOPPE, Mathias; VIANA, Bruno; ASCHEHOUG, Patrick; PAUPORTÉ, Thierry; TIGINYANU, Ion; POLONSKYI, Oleksandr; SONTEA, Victor; CHOW, Lee; KIENLE, Lorenz; ADELUNG, Rainer; FAUPEL, Franz; LUPAN, Oleg (Universitatea Tehnică a Moldovei, 2018)
    In this study, Ag-doped ZnO (ZnO:Ag) nanostructured films were functionalized with silver nanoparticles (Ag NPs), silver-platinum bimetallic nanoparticles (AgPt NPs) and silver-gold bimetallic NPs (AgAu NPs) using a gas ...
  • Microheaters for copper oxide-based gas sensors 
    ABABII, Nicolai; TROFIM, Viorel; LUPAN, Oleg (Tehnica UTM, 2020)
    This paper describes two procedures developed for obtaining microheaters for copper oxide-based gas sensors. Different types of substrates (glass, SiO2/Si and ceramic) are investigated, as well as different configurations ...
  • Nanosensors based on individual hybrid structures and their application in gas sensing at room temperature 
    POSTICA, Vasile; RASCH, Florian; SCHÜTT, Fabian; ADELUNG, Rainer; LUPAN, Oleg (Tehnica UTM, 2020)
    Because the commercialization of nanosensors in the field of gas sensing is still in its infancy, many efforts have been made to develop efficient methods to increase their performances. A special attention was paid to the ...
  • New vapor deposited dielectric polymer thin films for electronic applications 
    SCHRÖDER, Stefan; MAGARIU, Nicolae; STRUNSKUS, Thomas; ABABII, Nicolai; LUPAN, Oleg; FAUPEL, Franz (Technical University of Moldova, 2022)
    Dielectric materials are of great interest in a vast amount of applications ranging from cable insulation to advanced electronic devices. The emerging trend of device miniaturization is creating an increased demand for ...
