چکیده
We investigate the reflection near the reststrahlen band of the optical phonon in bulk GaAs in the time domain, using time-resolved terahertz spectroscopy. We find that the dynamics of the reflection measured for GaAs differs strongly from the reflection dynamics that would be expected for a TO phonon with a frequency-independent dephasing time.

Transient photoconductivity in GaAs as measured by time-resolved terahertz spectroscopy
The onset and decay of photoconductivity in bulk GaAs has been measured with 200-fs temporal resolution using time-resolved THz spectroscopy. A low carrier density (,2310 cm) with less than 100-meV kinetic energy was generated via photoexcitation. The conductivity was monitored in a noncontact fashion through absorption of THz ~far-infrared! pulses of several hundred femtosecond duration. The c...
متن کاملEnhanced Exciton–Phonon Coupling in Spherical GaAs Nanocrystals Studied by Selective Excitation Spectroscopy
Phonon-assisted exciton transitions in spherical GaAs nanocrystals embedded in SiO2 matrices have been studied by means of selective excitation spectroscopy. The optical and acoustic phononassisted optical transitions appear in the photoluminescence excitation, photoluminescence linenarrowing, and photoluminescence hole-burning spectra at low temperatures. Both direct (zerophonon) and phonon-as...
متن کاملObservation of Coherent Surface Optical Phonon Oscillations by Time-Resolved Surface Second-Harmonic Generation
We demonstrate a new time-domain surface phonon spectroscopy. We excite coherent surface optical phonons with an ultrashort laser pulse and probe the free-induction decay with time-resolved surface second-harmonic generation. For both clean GaAs (110) and (100) surfaces, the signals are remarkably large due to the highly localized electron-phonon interaction at the surface and the intrinsic sur...
متن کاملApplication of broadband terahertz spectroscopy in semiconductor nonlinear dynamics
Semiconductor nonlinearity in the range of terahertz (THz) frequency has been attracting considerable attention due to the recent development of high-power semiconductor-based nanodevices. However, the underlying physics concerning carrier dynamics in the presence of high-field THz transients is still obscure. This paper introduces an ultrafast, time-resolved THz pump/THz probe approach to stud...
متن کاملTime-resolved Characterization of Non-equilibrium Carrier Dynamics in Gallium Based III-V Materials and Devices
Ga-based III-V materials, such as, GaAs, GaN and AlGaN, have a wide-range of applications in the fields of high-speed, high-temperature, high-power and high-frequency electronic and optoelectronic devices, due to their unique physical properties. This thesis is devoted to the time-resolved characterization of ultrafast, nonequilibrium carrier and phonon dynamics in Ga-based III-V materials and ...
