  • About influences of different actions on spectra of impurity photoluminescence in GaAs 
    Litovchenko, N.M.; Prokhorovich, A.V.; Strilchuk, O.N. (Semiconductor Physics Quantum Electronics & Optoelectronics, 2001)
    Considered is the possibility to determine changes stimulated by external actions on a ratio between different luminescence center concentrations in GaAs crystals when using their photoluminescence spectra. It was shown ...
  • Analysis of luminescence method applicability for determination of Cd₁₋xZnxTe composition 
    Glinchuk, K.D.; Litovchenko, N.M.; Strilchuk, O.N. (Semiconductor Physics Quantum Electronics & Optoelectronics, 2003)
    Physical fundamentals are analyzed for the method of determination of Cd₁₋xZnxTe composition x from measurements of the luminescence band peak position, emission being caused by annihilation of bound exciton - shallow ...
  • Analysis of luminescence method for determination of Cd₁₋xZnxTe composition 
    Glinchuk, K.D.; Litovchenko, N.M.; Prokhorovich, A.V.; Strilchuk, O.N. (Semiconductor Physics Quantum Electronics & Optoelectronics, 2005)
    A detailed analysis of the method for determination of Cd₁₋xZnxTe composition x from measurements of 4.2 K peak position of the emission band induced by annihilation of excitons bound with neutral shallow acceptors is ...
  • Capture coefficients of free excitons by shallow acceptors and donors in gallium arsenide 
    Glinchuk, K.D.; Litovchenko, N.M.; Strilchuk, O.N. (Semiconductor Physics Quantum Electronics & Optoelectronics, 2003)
    An analysis of the 4.2 K exciton luminescence spectra of semi-insulating GaAs crystals with different concentrations of shallow acceptors (С) and donors (Si) is given. As a result, the 4.2 K capture coefficients of free ...
  • On the origin of 300 K near-band-edge luminescence in CdTe 
    Glinchuk, K.D.; Litovchenko, N.M.; Strilchuk, O.N. (Semiconductor Physics Quantum Electronics & Optoelectronics, 2003)
    A careful analysis of 300 K near-band-edge luminescence from bulk CdTe and cadmium telluride films is made. It is shown that: (i) the observed difference in 300 K peak positions of the near-band-edge luminescence hvm in ...
  • Stimulated by heating-up changes of lux-brightness characteristics of semi-in sulating speciallyundoped GaAs crystals 
    Litovchenko, N.M.; Prokhorovich, A.V.; Strilchuk, O.N. (Semiconductor Physics Quantum Electronics & Optoelectronics, 2001)
    It was shown that thermal treatment of semi-insulating specially undoped gallium arsenide leads to significant changes of lux-brightness characteristics of inter- impurity and impurity bands in the spectra of impurity ...
