  • Exciton condensation in quantum wells 
    Sugakov, V.I. (Физика низких температур, 2006)
    The theory of exciton condensation is given in two-dimensional systems under suggestion that condensation occurs in really space and condensed phase arises as a result of an attractive interaction between excitons. Due ...
  • Exciton condensation in quantum wells. Exciton hydrodynamics. The effect of localized states 
    Sugakov, V.I. (Condensed Matter Physics, 2014)
    The hydrodynamic equations for indirect excitons in the double quantum wells are studied taking into account 1) a possibility of an exciton condensed phase formation, 2) the presence of pumping, 3) finite value of the ...
  • Exciton density pattern formation in laser irradiated quantum wells under electrodes of various shapes 
    Tomylko, V.V.; Goliney, I.Yu.; Chernyuk, A.A.; Sugakov, V.I. (Физика низких температур, 2014)
    The condensation of indirect excitons in double quantum wells is studied in an electric field created by electrodes of different shapes. The finite value of the exciton lifetime, the pumping and nonuniformity of the electric ...
  • Influence of neutron irradiation on elctrooptical and structural properties of silicon 
    Groza, A.A.; Venger, E.F.; Varnina, V.I.; Holiney, R.Yu.; Litovchenko, P.G.; Matveeva, L.A.; Litovchenko, A.P.; Sugakov, V.I.; Shmatko, G.G. (Semiconductor Physics Quantum Electronics & Optoelectronics, 2001)
    Processes of structure defects formation, which accompanied by oxygen precipitation after a neutron irradiation (10¹⁵- 10¹⁹ n/cm²) and high-temperature treatment (800 - 1000°С) in CZ silicon, were investigated by the ...
  • Instabilities in binary compounds under irradiation 
    Mykhaylovskyy, V.V.; Sugakov, V.I. (Вопросы атомной науки и техники, 2000)
    A simulation of radiation-induced instability in binary semiconductor, such as GaAs, was fulfilled. The instability is connected with antisite defects accumulated. It was shown that the number of antisite defects in crystal ...
  • Investigation of the direct/indirect exciton transition in the double quantum well system based on Cd₁₋yMgyTe/ Cd₁₋xMnxTe in applied magnetic field 
    Lev, S.B.; Sugakov, V.I.; Vertsimakha, G.V. (Semiconductor Physics Quantum Electronics & Optoelectronics, 2007)
    The energy levels, wave functions, and lifetimes of direct and indirect excitons in a CdTe-based double quantum well system with non-magnetic (Mg) and magnetic (Mn) ions in a magnetic field are found. It is shown that, ...

    Kаrpenko, А.Ya.; Litovchenko, P.G.; Shevtsova, О.N.; Sugakov, V.I.; Vikhlii, G.A. (Физика низких температур, 2003)
    A jump-like increase of the resistance as a function of magnetic field is observed in indium arsenide samples irradiated by a particles with an energy of 80 MeV. The effect is detected at T < 5 K. The observed effect is ...
  • Ordered Dissipative Structures in Exciton Systems in Semiconductor Quantum Wells 
    Chernyuk, A.A.; Sugakov, V.I. (Symmetry, Integrability and Geometry: Methods and Applications, 2006)
    A phenomenological theory of exciton condensation in conditions of inhomogeneous excitation is proposed. The theory is applied to the study of the development of an exciton luminescence ring and the ring fragmentation at ...
  • Spin polarization in semimagnetic semiconductor two barrier spin filters 
    Lev, S.B.; Sugakov, V.I.; Vertsimakha, G.V. (Semiconductor Physics Quantum Electronics & Optoelectronics, 2007)
    The spin-dependent tunneling of electrons through the CdMgTe-based twobarrier resonant tunneling system with a semimagnetic CdMnTe well is studied. The level splitting in the semimagnetic well under an external magnetic ...
