The ultrafast inter-conduction band carrier dynamics in 6H–SiC was observed by using pump and probe transient absorption technique. Probe wavelength dependence of the bleaching was compared with the steady-state absorption profiles for polarizations parallel and perpendicular to the c axis, and these bleachings were ascribed to the decrease of electron populations in the lowest conduction band. The relaxation time from the higher to the lowest conduction band due to the inter-conduction band electron–phonon scattering is 1.25 ps. © 2001 American Institute of Physics.

    We report on the optical orientation of singly charged exciton X+ in a single self-assembled InAs/GaAs quantum dot. We show that the hyperfine interaction with the nuclei is responsible for a partial spin relaxation. This effect manifests only under modulated excitation polarization, while under...

    : We discuss theoretically the relaxation of charge fluctuations in polyampholyte solutions. It has been shown previously by some of us (J. Wittmer et al. Europhys.

    This paper presents a theory of relaxation for systems of spins that are metastable as a result of unimolecular spin decay. A complex Hamiltonian is used to describe the spin decay. Redfield’s theory [Adv. Magn. Reson. 1, 1 (1965)] which describes relaxation in stable spin systems, is...
