  • Gaşin, Petru; Cuculescu, Elmira; Evtodiev, Igor; Anghel, Sergiu; Caraman, Mihail (CEP USM, 2007)
    GaS and GaSe doped with Cu thin films have been deposited by "flash" evaporation. The thickness of the layers varied from 138 to 1450 nm. The absorption spectra in the fundamental band edge region have been studied. The ...
  • Evtodiev, Igor (CEP USM, 2009)
    In this work is investigated the light absorption in the InSe layer of the heterostructure as well as the InSe layer from the interface of the junction Bi2O3-InSe throughtheabsorption, reflection spectrums and photoluminescence ...
  • Hartnagel, Hans Ludwig; Sirkeli, Vadim (Springer Nature, 2019)
    Terahertz (THz) waves refer to the electromagnetic radiation in the frequency range from 0.1 to 10 THz, which corresponds to the wavelengths from 3 mm to 30 µm, respectively. This spectral region, called also as “T-gap”, ...
  • Sprincean, Veaceslav; Paladi, Adrian; Bulimaga, Tatiana; Paladi, Florentin (IEEE, 2020)
    Advanced physical technologies developed in the research laboratories of the Moldova State University (MSU) are used in the monitoring of environmental factors with the application of UVS (Unmanned Vehicle Systems). The ...
  • Barsuk, Alexander; Banichuk, Nikolay; Ivanova, S.Y.; Tuovinen, Tero; Makeev, Evgeni; Jeronen, Juha (Taylor and Francis, 2018)
    We consider an infinite, homogenous linearly elastic beam resting on a system of linearly elastic supports, as an idealized model for a paper web in the middle of a cylinder-based dryer section. We obtain closed-form ...
  • Boldyrev, S. I.; Paladi, Florentin (American Scientific Publishers, 2009)
    The influence of vibronic interactions on the magnetic properties of the tetrameric square-planar mixed-valence d0-d0-d1-d1 cluster with two-electron transfer is investigated. The dynamic vibronic problem has been solved ...
  • Sergentu, V.V.; Prilepov, V.; Zalamai, V.; Gashin, P. (Academia de Știinițe a Moldovei, 2016)
    A nanostructured disordered ice Ih fraction in a water environment is theoretically investigated. The disordered ice fraction is taken into account as a nanocomposite consisting of a substance and a vacuum. The pattern of ...
  • Korotcenkov, Ghenadii; Brinzari, Vladimir; Nehasil, Vaclav (Elsevier, 2021)
    The effect of surface modification of In2O3 films by rhodium atoms deposited by electron beam sputtering on the XP spectra is considered. The surface coverage with rhodium ranged from 0 to 0.1 ML. It was shown that the ...
  • Korotcenkov, Ghenadii; Brinzari, Vladimir; Hanyš, P.; Nehasil, V. (John Wiley and Sons, 2018)
    In this paper, we have analyzed the effect of the rhodium surface modification on the surface state of SnO2 films. SnO2 films, subjected for the surface modification, were deposited by spray pyrolysis, while Rh was deposited ...
  • Colibaba, Gleb (Elsevier, 2019)
    The present investigation is a theoretical study of doping efficiency of ZnO crystals grown by using compound chemical vapor transport (CVT) agents based on HCl and doped by oxides of various metals in the growth process. ...
  • Sirkeli, Vadim; Hartnagel, Hans (Elsevier, 2021)
    This chapter reviews the recent progress of the theoretical and experimental studies of ZnO-based structures such as quantum cascade lasers, resonant-tunneling diodes, and quantum well detectors and their applications for ...
  • Botnariuc, Vasile; Gorceac, Leonid; Coval, Andrei; Cinic, Boris; Gaugas, Petru; Chetrus, Petru; Lungu, Ion; Raevschi, Simion (Springer Nature, 2020)
    The ZnO thin layers were grown on glass, InP and pInP-nCdS substrates from zinc acetate dissolved in water-acetic acid-methanol solution having a molarity of 0.2 M by using the spray method in the argon flow in the temperature ...
  • Sirkeli, Vadim; Hartnagel, Hans; Yilmazoglu, O.; Preu, S. (Springer Nature, 2020)
    In this paper we report on the numerical study of the terahertz devices based on metal oxide semiconductors and its application in biology and medicine. We also report on the recent progress of the theoretical and experimental ...
  • Sirkeli, Vadim; Hartnagel, Hans (Elsevier, 2019)
    High-power terahertz sources operating at room-temperature are promising for many applications such as explosive materials detection, non-invasive medical imaging, and high speed telecommunication. Here we report the results ...
  • Sirkeli, Vadim; Nedeoglo, Natalia; Nedeoglo, Dmitrii; Yilmazoglu, Oktay; Hajo, Ahid; Preu, Sascha; Kuppers, Franko; Hartnagel, Hans (CEP USM, 2021)
    We report on the selection of contact metallisations for ZnSe-based metal-semiconductor-metal ultraviolet photode- tectors. Our evaluation is based on Ni/Au, Cr/Au, and hybrid Ag-nanowire contacts. Low values of dark ...
