    Era moderna a electronicii a început cu o dezvoltare accelerată înainte de cel de al doilea razboi mondial şi a continuat după acesta, perioadă în care componentele electronice de la acea vreme (relee, rezistoare. ...
  • PENIN, Alexandru; SIDORENKO, Anatoly (Institutul de Inginerie Electronică şi Nanotehnologii "D. Ghiţu" al AŞM, 2015)
    For an active multi-port network of direct current, as a model of distributed power supply system, the problem of recalculation of the changeable load currents is considered. Conditions of utilization of projective coordinates ...
  • CARSTENSEN, J.; CHRISTOPHERSEN, M.; LÖLKES, S.; OSSEI-WUSU, E.; BAHR, J.; LANGA, S.; POPKIROV, G.; FÖLL, H. (WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim, 2005)
    While electrochemical etching of small samples in the 1 cm region is relatively easy, this is not true for large areas, i.e. standard wafer sizes up to 300 mm. The paper outlines the specific demands and difficulties in ...
  • ZDRAVKOV, Vladimir Ilich; MORARI, Roman Andreevich; SIDORENKO, Anatoli Sergeevich (Springer Nature Switzerland, 2008)
    High quality Nb nanoscale films of large area (7 × 80 mm2) and constant thickness were deposited by DC-magnetron sputtering in commercial “Leybold Z400” vacuum system. Homogeneity and proper thickness of the Nb layer ...
  • SYRBU, N. N.; PARVAN, V. I.; URSAKI, V. V. (ELSEVIER, 2012)
    Exciton states with a large oscillator strength (transverse–longitudinal splitting of 50meV) and binding energy of 290meV have been observed in PbGa2S4 crystals. The ground exciton states are stable up to the room temperature. ...
  • ŢURCAN, Rina (Institutul de Relaţii Internaţionale din Moldova, 2010)
    Currently the contribution of tourism in national economy is relatively insignificant. Low quality level of accommodation capacity and the income from tourist place Moldova among the countries where tourism is poorly ...
