    We demonstrate optical control of the LO phonon-plasmon coupled (LOPC) modes in GaAs by using a femtosecond pump-pulse pair. The relaxation time of the plasmonlike LOPC mode significantly depends on the separation time (Δt) of the pump-pulse pair. Especially it is maximized when Δt...

    We study the origin of the boson peak and an associated mechanism for acoustic-phonon broadening (below the peak) in glasses exhibiting a high-frequency sound above the peak. The origin is related to the Ioffe-Regel crossover for inelastic (resonant) scattering of acoustic phonons from harmonic...

    A variational method and a memory function approach are adopted to investigate the electron mobility parallel to the interface for a model AlxGa1-xAs/GaAs heterojunction and its pressure effect by considering optical phonon modes (including both of the bulk longitudinal optical (LO) in the...

    We present a model calculation of the lattice thermal conductivity of ZrNiSn-based half-Heusler thermoelectric compounds for temperatures where phonon scattering is dominated by Umklapp and point defect scattering. The difference in mass between impurity and host atoms dominates point defect...

    The phonon spectra of thin freestanding, hydrogen passivated, Ge nanowires are calculated by ab initio techniques. The effect of confinement on the phonon modes as caused by the small diameters of the wires is investigated. Confinement causes a hardening of the optical modes and a softening of...

  • Phonon scattering at a rough interface between two fcc lattices. Zhao, Hong; Freund, Jonathan B. // Journal of Applied Physics;Jan2009, Vol. 105 Issue 1, p013515 

    Elastic phonon scattering at an atomically rough interface that separates two fcc lattice leads is computed via a Green’s function method. Results are compared to specular and diffuse phonon scattering models, both of which are widely used in the numerical simulations of phonon Boltzmann...

    We investigate theoretically the effect of nonparabolic band structure on the electron-confined LO-phonon scattering rate in GaAs-Al0.45Ga0.55As superlattice. Using the quantum treatment, the new wave function of electron miniband conduction of superlattice and a reformulation of the slab model...

    Ultra-fast optical measurements of few-layer suspended graphene films grown by chemical vapor deposition were performed with femtosecond pump–probe spectroscopy. The relaxation processes were monitored in transient differential transmission (Δ T/ T) after excitation at two different...
