Dynamical Corrections to Spin Wave Excitations in Quantum Wells due to Coulomb Interactions and Magnetic Ions
Cynthia Aku-Leh, Florent Perez, Bernard Jusserand +2
We have measured dispersions of spin-flip waves and spin-flip single-particle excitations of a spin polarized two-dimensional electron gas in a CdMnTe quantum well using resonant R…
Measuring the spin polarization and Zeeman energy of a spin-polarized electron gas: Comparison between Raman scattering and photoluminescence
Cynthia Aku-Leh, Florent Perez, Bernard Jusserand +5
We compare resonant electronic Raman scattering and photoluminescence measurements for the characterization of a spin-polarized two-dimensional electron gas embedded in $\text{Cd}_…
Long-lived optical phonons in ZnO studied with impulsive stimulated Raman scattering
C. Aku-Leh, J. Zhao, R. Merlin +2
The anharmonic properties of the low-frequency E2 phonon in ZnO were measured using impulsive stimulated Raman scattering. At 5 K, the frequency and lifetime are (2.9787 +/- 0.0002…
Ultrafast optical generation of coherent phonons in CdTe1-xSex quantum dots
A. V. Bragas, C. Aku-Leh, S. Costantino +3
We report on the impulsive generation of coherent optical phonons in CdTe0.68Se0.32 nanocrystallites embedded in a glass matrix. Pump probe experiments using femtosecond laser puls…
