Intersubband relaxation of two-dimensional electrons in heterostructures.
%'e calculate the lifetime of a nonequilibrium electron in the first excited subband in the lowdensity heterostructure where this photocreated carrier occurs at the last stage of its cooling. The electron interaction with acoustic phonons gives the dominant intersubband relaxation mechanism, if the intersubband energy splitting and the Fermi energy splitting are relatively small, 1 ) e&/Azo ) 0...
متن کاملEscape dynamics of photoexcited electrons at catechol:TiO2„110..
Ultrafast electron escape dynamics following excitation of the interfacial charge transfer complex of catechol prepared on the rutile TiO2 110 surface was investigated with femtosecond two-photon photoemission 2PPE . Laser pulses were generated with two noncollinear optical parametric amplifiers operated simultaneously at a repetition rate of 150 kHz delivering a cross-correlation function with...
متن کاملStimulated scattering and lasing of intersubband cavity polaritons.
We present a microscopic theory describing the stimulated scattering of intersubband polariton excitations in a microcavity-embedded two-dimensional electron gas. In particular, we consider the polariton scattering induced by the interaction with longitudinal optical phonons. Our theory demonstrates the possibility of final-state stimulation for the scattering of such composite excitations, acc...
متن کاملGeneration and transport of photoexcited electrons in single-crystal diamond
We report time-dependent photocurrent and transport measurements of sub-bandgap photoexcited carriers in nitrogen-rich type Ib , single-crystal diamond. Transient carrier dynamics are characteristic of trapping conduction with long charge storage lifetimes of 3 hours. By measuring the photoexcited Hall effect, we confirm that the charge carriers are electrons and by varying the excitation energ...
متن کاملFano profile in the intersubband terahertz response of photoexcited GaAs/AlGaAs quantum wells
In our work we probe the conduction intersubband transition of an undoped GaAs/Al0.34Ga0.66As multiple quantum well via broadband terahertz pulses after resonant photoexcitation at the 1s heavy-hole exciton. The pump-induced change in the transmitted terahertz field shows a strong beating. In the frequency domain this results in an asymmetric Fano-like line shape for the intersubband resonance ...
