  • 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 ...
  • Exciton effects in band-edge electroluminescence of silicon barrier structures 
    Sachenko, A.V.; Gorban, A.P.; Korbutyak, D.V.; Kostylyov, V.P.; Kryuchenko, Yu.V.; Chernenko, V.V. (Semiconductor Physics Quantum Electronics & Optoelectronics, 2004)
    A theoretical analysis of the band-edge electroluminescence efficiency in silicon diodes and p-i-n-structures has been made. We have shown that maximal possible efficiency can achieve 10 % both at room and liquid nitrogen ...
  • 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 low-temperature annealing on the state of CdTe surface 
    Parfenyuk, O.A.; Ilashchuk, M.I.; Chupyra, S.M.; Burachek, V.R.; Korbutyak, D.V.; Krylyuk, S.G.; Vakhnyak, N.D. (Semiconductor Physics Quantum Electronics & Optoelectronics, 2005)
    Influence of low-temperature annealing on electrical and luminescent properties of semi-insulating n-CdTe:Sn is studied. It is shown that annealing at T ≥ 453 K modifies a near-surface layer of the crystals and this enhances ...
