  • OPTICAL PROPERTIES OF CRYSTALS GaSe AND InSe DOPED WITH Cu 
    Evtodiev, Igor; Cuculescu, Elvira; Caraman, Mihail; Anghel, Sergiu; Petrov, M. (2005)
    The anisotropy of absorption spectra in the range of the margin of fundamental band of the crystals GaSe and InSe doped with Cu in the percentage quantities up to 0.5 % at. from which the implementation mechanism of ...
  • UNELE PROPRIETĂŢI OPTICE ALE STRATURILOR SUBŢIRI DE GaSe ŞI GaS DOPATE CU Cu 
    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 ...
