متن کاملNonlinear Interactions among Solar Acoustic Modes
We evaluate the rates at which nonlinear interactions transfer energy among the normal modes of a planeparallel, stratified atmosphere. The atmosphere resembles the outer part of the Sun including the convection zone and the optically thin region above the photosphere up to the temperature minimum. The acoustic modes are assigned energies such that their photospheric velocities match those of t...
متن کاملAcoustic phonon modes and dispersion relations of nanowire superlattices.
We study theoretically acoustic phonon modes in nanowire superlattices (NWSLs) composed of cubic materials. We classify the acoustic phonon modes in rectangular and square cross-section NWSLs, based on group theory. For NWSLs consisting of GaAs and AlAs, we calculate numerically the dispersion relations of each phonon mode and corresponding displacement fields. We examine the effects of both th...
متن کاملThe observation of the low-frequency acoustic phonon torsional modes in nanocrystalline silicon
Low-frequency Raman spectra of the porous structure formed on C-implanted silicon were examined using the 514.5 and 488 nm lines of Ar laser. The sharp low-frequency Raman peaks were observed with narrow linewidth and large intensity. According to usual vibration theory of the elastic body and related symmetry analysis, they are identified as the localized acoustic phonon torsional modes result...
