The ultrafast coupling dynamics of coherent optical phonons and the photoexcited electron-
hole plasma in the indirect gap semiconductor GaP are investigated by experiment and …

In the investigation of the nonequilibrium ultrafast dynamics of the coherent phonon-
plasmon coupled modes in a polar semiconductor, we predict theoretically that their …

We present a microscopic theory of plasmon-phonon oscillations created by ultrafast optical
excitation in polar semiconductors. Our analysis is based on the equations for the optical …

We present a joint experimental theoretical study of the coupling of coherent phonons in
bulk GaAs with a nonequilibrium electron-hole plasma following photoexcitation at the E 1 …

The interaction of photoexcited electron–hole plasma with impulsively excited coherent
longitudinal optical phonons in GaAs was investigated via time-resolved second-harmonic …

We report on the ultrafast decay of coherently excited plasmon-phonon coupled modes in a
highly doped n-GaAs. Coherent oscillations of the upper branch (L+) as well as the lower …

The coupling between femtosecond laser-excited coherent LO phonons and plasmon in
GaAs was investigated in real time via two-pump time-resolved second-harmonic …

The LO-phonon–hole-plasmon coupling is investigated for p-type III-V semiconductors. Due
to a large carrier damping, only one coupled LO-phonon–plasmon mode (CPPM) appears …

Coherent longitudinal optical (LO) phonons are generated through nonlinear excitation by
laser light. It is observed that the vibronic sideband structure associated with coherent LO …

The interaction between small-wave-vector, longitudinal-optic (LO) lattice vibrations and free-
hole plasmas in Be-doped p-type GaAs is studied with use of nonresonant, allowed Raman …
