  • Characteristics of confined exciton states in silicon quantum wires 
    Korbutyak, D.V.; Kryuchenko, Yu.V.; Kupchak, I.M.; Sachenko, A.V. (Semiconductor Physics Quantum Electronics & Optoelectronics, 2003)
    We have studied theoretically the combined effect of quantum confinement and "dielectric enhancement" on the characteristics of the exciton ground state in quasi-1D silicon nanowires. Consideration has been made within ...
  • Excitons and trions in spherical semiconductor quantum dots 
    Kupchak, I.M.; Kryuchenko, Yu.V.; Korbutyak, D.V. (Semiconductor Physics Quantum Electronics & Optoelectronics, 2006)
    An original iterative procedure has been developed to obtain energy spectrum of neutral and charged excitons (positive and negative trions) in spherical semiconductor quantum dots (QD) imbedded into a dielectric material. ...
  • Influence of g-irradiation on photoluminescence spectra of CdTe:Cl 
    Vakhnyak, N.D.; Krylyuk, S.G.; Kryuchenko, Yu.V.; Kupchak, I.M. (Semiconductor Physics Quantum Electronics & Optoelectronics, 2002)
    Photoluminescence properties of high-resistivity CdTe:Cl crystals irradiated with g-rays have been studied. An enhancement of near-edge luminescence intensity is observed after a low dose g-irradiation (D < 10 kGy). For ...
  • Vibrational states of hexagonal ZnO doped with Co 
    Kupchak, I.M.; Serpak, N.F.; Strelchuk, V.V.; Korbutyak, D.V. (Semiconductor Physics Quantum Electronics & Optoelectronics, 2015)
    Vibrational density of states of 12.5% cobalt doped bulk hexagonal ZnO has been studied using the density functional theory method. It has been shown that introduction of cobalt into ZnO leads to appearance of additional ...
