  • Effect of deposition rate and substrate microstructure on gas sensitivity of Te thin films 
    MOCREAC, Olga (Inženjersko društvo za koroziju, Beograd, 2019)
    Tellurium thin films have been prepared using different rates (0.1 ÷ 30 nm/s) by physical deposition in vacuum on glassy, sintered alumina and electrochemically nanostructured Al2O3 substrates. The sensitivity to nitrogen ...
  • Effect of nanostructuring to response kinetics of tellurium thin films by nitrogen dioxide sensing 
    TSIULYANU, Dumitru; CIOBANU, Marina; MOCREAC, Olga (Taylor & Francis, Inc. Molecular Crystals and Liquid Crystals, 2020)
    The work is conducted to clarify the effect of structural dimensionality of tellurium thin films on gas (NO2) sensing at room temperature. Nanostructuring of Te films has been realized via three methods (Fig.1): ...
  • Gas sensing characterization of tellurium thin films by Kelvin probe technique 
    TSIULYANU, D.; MARIAN, S.; MOCREAC, O. (Institutul de Fizică Aplicată al AŞM, 2012)
    In this paper, the change of work function ( Δφ ) of the tellurium thin films was studied in response to different concentrations of nitrogen dioxide, carbon oxide, ozone and water vapor using a KP with a gold grid reference ...
  • Gas-sensing features of nanostructured tellurium thin films 
    TSIULYANU, Dumitru (Beilstein Institute for the Advancement of Chemical Sciences (Germany), 2020)
    Nanocrystalline and amorphous nanostructured tellurium (Te) thin films were grown and their gas-sensing properties were investigated at different operating temperatures with respect to scanning electron microscopy and X-ray ...
  • Impedance spectroscopy of sensitive to harmful gases tellurium thin films 
    TSIULYANU, D.; MOCREAC, O. (Forum of Chalcogeniders, 2011)
    Impedance spectra of tellurium thin films with interdigital platinum electrodes have been investigated in different gaseous media. For the first time it is pointed out that tellurium films exhibit sensitivity to H2 at room ...
  • Impedance Spectroscopy of Tellurium Thin Films Sensitive to NO2 
    TSIULYANU, D.; MOCREAC, O. (Springer Nature Switzerland, 2011)
    Impedance spectra of tellurium thin films with interdigital platinum electrodes have been measured in dry synthetic air and gaseous media with nitrogen dioxide. Analyses of Cole-Cole plots allowed to evaluate the characteristic ...
  • Nanocrystalline Tellurium Films: Fabrication and Gas Sensing Properties 
    TSIULYANU, D.; MORARU, A. (Springer Nature Switzerland, 2015)
    A brief review of achievements in the fabrication of nanostructured tellurium thin films for applications in sensor technology is reported, paying particular attention to physical growth of nanocrystalline films in vacuum.
  • Tellurium Thin Films in Sensor Technology 
    TSIULYANU, D. (Springer Nature Switzerland, 2011)
    An extensive review of the application of tellurium thin films in sensor technology is reported and discussed. Along with the traditional use of Te films in photo and strain sensitive devices, their modern application in ...
