  • Excitons in Nanosystems Consisting of Semiconductor Quantum Dots 
    Pokutnyi, S.I.; Gorbyk, P.P.; Makhno, S.M.; Prokopenko, S.L.; Mazurenko, R.V. (Наносистеми, наноматеріали, нанотехнології, 2017)
    As found, within the band gap of the quantum dot of zinc selenide, a zone of exciton states located at the bottom of the conduction band appears. As shown, a decrease in the band gap width for this nanosystem is conditioned ...
  • New Quasi-Atomic Nanoheterostructures: Superatoms and Excitonic Quasi-Molecules 
    Pokutnyi, S.I.; Gorbyk, P.P.; Salejda, W.; Persano Adorno, D.; Khasanov, O.K.; Fedotova, O.M. (Наносистеми, наноматеріали, нанотехнології, 2016)
    In this review, the state-of-the-art of research of artificial atoms (superatoms or quasi-atomic nanoheterostructures) and more complex nanostructures based on them—synthetic molecules is discussed, a new model of an ...
  • Spectrum of electron-hole pair in quantum dots of a semiconductor nanolaser: theory 
    Pokutnyi, S.I. (Semiconductor Physics Quantum Electronics & Optoelectronics, 2004)
    A theory of laser generation on size-quantization levels in semiconductor quantum dots put in a semiconductor matrix is developed. The size of quantum dots mass of which comprises the active sphere of an injection laser ...
  • Theoretical investigation of light absorption and scattering by nanoparticles 
    Pokutnyi, S.I.; Kovalchuk, V.V. (Semiconductor Physics Quantum Electronics & Optoelectronics, 2000)
    In the framework of the dipole approximation we predict theoretically high magnitudes of: (1) oscillator strength transitions, and (2) the resonance light cattering (σss(w, a)) and absorption (σabs(ω, a)) cross-sections. ...
  • The theory of exciton states in quasi-zero-dimensional semiconductor systems 
    Pokutnyi, S.I. (Semiconductor Physics Quantum Electronics & Optoelectronics, 2006)
    For a semiconductor quantum dot (QD), the contributions made to the exciton energy spectrum by the electron and hole kinetic energies, the energy of Coulomb interaction between them, and the energy of their polarization ...
