Carrier Thermalization and Biexciton Formation in a Polar ZnO/ZnMgO Quantum Well Probed by Ultrafast Broadband Spectroscopy
Daniel O. Siebadji Tchuimeni, Marc Ziegler, Olivier Crégut +4
We investigate the ultrafast dynamics of excitons in a 2.6 nm-thick quantum well grown on a c-axis sapphire substrate, using non-degenerate time-…
Nonlinear strong coupling between sub-band excitons: a new coherent path for ultrafast relaxation
Pierre Gilliot, Bertrand Yuma, Marc Ziegler +2
We demonstrate theoretically and experimentally that the nonlinear interaction between excitations whose harmonic energies coincide gives rise to a strong coupling that opens a new…
Biexciton, single carrier, and trion generation dynamics in single-walled carbon nanotubes
Bertrand Yuma, Stéphane Berciaud, Jean Besbas +10
We present a study of free carrier photo-generation and multi-carrier bound states, such as biexcitons and trions (ionized excitons), in semiconducting single-walled carbon nanotub…
