  • Electrochemical Nanostructuring of CuInS2 Bulk Crystals 
    MONAICO, Eduard; URSAKI, Veaceslav; ZALAMAI, Victor; MASNIK, Alisa; SYRBU, Nicolae; BURLACU, Alexandru (Technical University of Moldova, 2011)
    We show that chalcopyrite CuInS2 crystals can be nanostructured by electrochemical treatment in an aqueous HCl solution. In order the crystals to become suitable for electrochemical nanostructuring they are subjected to ...
  • Fabrication of Porous Nanostructures by Design 
    MONAICO, Eduard; MONAICO, Elena; URSAKI, Veaceslav; TIGINYANU, Ion (Technical University of Moldova, 2017)
    We report on the application of special design of masks for the purpose of electrochemical etching of InP single crystals which enables one to change in a controlled fashion the direction of propagation of pores, including ...
  • Influence of Metal Deposition on Electrochemical Impedance Spectra of Porous GaP and GaN Semiconductors 
    ANICAI, Liana; GOLGOVICI, Florentina; MONAICO, Eduard; URSAKI, Veaceslav; PRODANA, Mariana; ENACHESCU, Marius; TIGINYANU, Ion (Technical University of Moldova, 2017)
    A comparative analysis of electrochemical impedance spectroscopy (EIS) characterization is performed in porous GaN and GaP templates with and without metal nanostructured layers deposited by pulsed electroplating. The ...
  • Photoconductivity relaxation in nanostructured InP 
    POSTOLACHE, Vitalie; MONAICO, Eduard; BORODIN, Eugeniu; LUPAN, Oleg; URSAKI, Veaceslav; ADELUNG, Rainer; NIELSH, Kornelius; TIGINYANU, Ion (Tehnica UTM, 2014)
    We show that long-duration-photoconductivity decay (LDPCD) and persistent photoconductivity (PPC) in porous InP structures produced by anodization of InP substrates can be controlled through the control of their morphology. ...
  • Pulsed Electroplating of Metal Nanoparticles form DODUCO Electrolytes 
    MONAICO, Eduard; BRINCOVEANU, Oana; MESTERCA, Raluca; URSAKI, Veaceslav; PRODANA, Mariana; ENACHESCU, Marius; TIGINYANU, Ion (Technical University of Moldova, 2017)
    The mechanisms of Au deposition on InP porous substrates during a pulsed electroplating process are investigated by means of Topography imaging and Current Mapping measurements. The obtained results confirm the formation ...
