  • Estimation of electron temperature in heated metallic nanoparticle 
    Grigorchuk, N.I. (Condensed Matter Physics, 2017)
    A method is proposed for determining the temperature of hot electrons in a metallic nanoparticle embedded in a dielectric matrix under ultrashort laser pulses irradiation. The amplitude and power of the longitudinal spherical ...
  • Influence of phonon dispersion on exciton damping in ionic crystals 
    Grigorchuk, N.I. (Semiconductor Physics Quantum Electronics & Optoelectronics, 2001)
    The manifestation of phonon dispersion on frequency and temperature dependence of exciton damping is investigated theoretically for the models of crystal with the large and small exciton radii. The correlation between the ...
  • Plasmon resonance sensitivity in fine metal particles 
    Grigorchuk, N.I. (Condensed Matter Physics, 2014)
    The sensitivity of the wavelength position of the surface plasmon resonances in a prolate and oblate fine metal particles to the refractive index of an embedding solution, a particle shape, and electron temperature is ...
  • Polarization operator of phonons in quadratic approximation 
    Grigorchuk, N.I. (Semiconductor Physics Quantum Electronics & Optoelectronics, 2000)
    Using the method of the retarded Green function the polarization operator of phonons has been calculated with the simultaneous account for the linear and quadratic terms in the Hamilton operator of exciton-phonon interaction. ...
  • Temperature dependence of plasmon resonances in spheroidal metal nanoparticles 
    Grigorchuk, N.I. (Condensed Matter Physics, 2013)
    The effect of the electron temperature on both the light absorption and the scattering by metal nanoparticles (MNs) with excitation of the surface plasmon electron vibrations is studied in the framework of the kinetic ...
