  • Acoustic properties of cylindrical nanowires with the elastically dissimilar barriers 
    NIKA, Denis L.; POKATILOV, Evgenii P.; BALANDIN, Alexander A. (Technical University of Moldova, 2005)
    We have theoretically investigated the effect of the coating made of the elastically dissimilar material on the acoustic phonon properties of semiconductor nanowires. It is shown that the acoustic impedance mismatch at the ...
  • Acoustical properties of rectangular quantum heterowires with clamped outer surfaces 
    ZINCENCO, Nadejda D.; NIKA, Denis L.; Al-SABAYLEH, Moayad (Technical University of Moldova, 2005)
    We had been theoretically studied the acoustic phonon spectra and group velocities of the phonons in the rectangular GaN nanowire with clamped outer surfaces, covered with elastically dissimilar barriers. The elastic ...
  • Many-cloud phonon propogators in the case of acoustical phonons 
    DIGOR, D. F. (Technical University of Moldova, 2005)
    In the High Temperature Superconductors we consider the system of correlated electrons which interect with phonons. In the theory of such sistems an effective way to describe correlation effects of electrons is based on ...
