  • About the nature of diffusion anisotropy in CdS crystals 
    Borkovskaya, L.V.; Dzhumaev, B.R.; Khomenkova, L.Yu.; Korsunskaya, N.E.; Markevich, I.V.; Sheinkman, M.K. (Semiconductor Physics Quantum Electronics & Optoelectronics, 2000)
    Electrodiffusion of copper into nominally undoped high-resistivity CdS crystals at 250-400°C has been investigated. A strong diffusion anisotropy has been observed, copper diffusion in perpendicular to the c-axis direction ...
  • Effect of the desorption process on photoluminescence excitation spectra of porous silicon 
    Torchinskaya, T.V.; Korsunskaya, N.E.; Khomenkova, L.Yu.; Dzhumaev, B.R.; Many, A.; Goldstein, Y.; Savir, E. (Semiconductor Physics Quantum Electronics & Optoelectronics, 1998)
    Photoluminescence (PL), photoluminescence excitation (PLE) and FTIR methods were used to study the PL excitation mechanism in porous silicon (PS). Two types of PLE spectra were observed, consisting of two (visible and ...
  • Metastable interstitials in CdSe and CdS crystals 
    Borkovska, L.V.; Bulakh, B.M.; Khomenkova, L.Yu.; Korsunska, N.O.; Markevich, I.V. (Semiconductor Physics Quantum Electronics & Optoelectronics, 2003)
    An "anomalous" defect drift in external electric field, namely, transport of acceptorlike centres from the anode to the cathode, has been observed in CdS:Cu, CdS:Ag and nominally undoped CdSe crystals at 350-700 K. The ...
  • Photo-enchanced defect reactions in CdS:Ag crystals 
    Khomenkova, L.Yu.; Markevich, I.V. (Semiconductor Physics Quantum Electronics & Optoelectronics, 2002)
    Two reversible photo-enhanced defect reactions proceeding under visible light illumination have been found in CdS:Ag crystals. The first process leads to the increase of crystal photosensitivity, which has been shown to ...
  • Silver-related local centres in cadmium sulfide 
    Borkovskaya, L.V.; Bulakh, B.M.; Khomenkova, L.Yu.; Markevich, I.V. (Semiconductor Physics Quantum Electronics & Optoelectronics, 2001)
    Silver-related defects and their diffusion in CdS crystals were investigated. The impurity was introduced in the crystal and extracted from it under electric field Ed = 10² V/cm at T = 300-450°C both parallel and perpendicular ...
  • Structure and luminescence study of nanoporous silicon layers with high internal surface 
    Makara, V.A.; Melnichenko, M.M.; Svezhentsova, K.V.; Khomenkova, L.Yu.; Shmyryeva, O.M. (Semiconductor Physics Quantum Electronics & Optoelectronics, 2003)
    In this work, the technique of formation of homogeneous nanoporous silicon layers with high internal surface on solar cell substrates by stain etching is developed. Emission and structure properties of such layers were ...
  • The nature of red emission in porous silicon 
    Khomenkova, L.Yu.; Korsunska, N.E.; Bulakh, B.M.; Sheinkman, M.K.; Stara, T.R. (Semiconductor Physics Quantum Electronics & Optoelectronics, 2005)
    The photoluminescence spectra of porous silicon at 77 and 300 K and their transformation during aging were investigated. The competition of two radiative recombination channels that have a common excitation mechanism was ...
