The role of excitons and trions on electron spin polarization in quantum wells
P. Aceituno, A. Hernandez-Cabrera
We have studied the time evolution of the electron spin polarization under continuous photoexcitation in remotely n-doped semiconductor quantum wells. The doped region allows us to…
Negative lateral conductivity of hot electrons in a biased superlattice
A. Hernandez-Cabrera, P. Aceituno, F. T. Vasko
Nonequilibrium electron distribution in a superlattice subjected to a homogeneous electric field (biased superlattice with equipopulated levels) is studied within the tight-binding…
Electron energy spectrum and density of states for non-symmetric heterostructures in an in-plane magnetic field
A. Hernandez-Cabrera, P. Aceituno, F. T. Vasko
Modifications of spin-splitting dispersion relations and density of states for electrons in non-symmetric heterostructures under in-plane magnetic field are studied within the enve…
Trion dynamics in coupled double quantum wells. Electron density effects
P. Aceituno, A. Hernandez-Cabrera
We have studied the coherent dynamics of injected electrons when they are either free or bounded both in excitons and in trions (charged excitons). We have considered a remotely do…
Temporal stimulated intersubband emission of photoexcited electrons
F. T. Vasko, A. Hernandez-Cabrera, P. Aceituno
We have studied the transient evolution of electrons distributed over two levels in a wide quantum well, with the two levels below the optical phonon energy, after an ultrafast int…
Coherent oscillations of electrons in tunnel-coupled wells under ultrafast intersubband excitation
A. Hernandez-Cabrera, P. Aceituno, F. T. Vasko
Ultrafast intersubband excitation of electrons in tunnell-coupled wells is studied depending on the structure parameters, the duration of the infrared pump and the detuning frequen…
