Interplay between Sb flux and growth temperature during the formation of GaSb islands on GaP

S. El Kazzi, L. Desplanque, X. Wallart, Y. Wang, P. Ruterana

We investigate the influence of the Sb flux on the growth of GaSb islands on a highly mismatched (001) GaP substrate. Between low and medium Sb flux values, standard kinetics drives the GaSb island formation and their relaxation is progressively favored by 90° misfit dislocations at the GaSb/GaP…

Level repulsion and evanescent waves in sonic crystals

V. Romero-Garcia, Jerome O. Vasseur, Anne-Christine Hladky, Lluis Miquel Garcia-Raffi, J.V. Sanchez-Perez

This work theoretically and experimentally reports the evanescent connections between propagating bands in periodic acoustic materials. The complex band structures obtained by solving for the k(ω) problem reveal a complete interpretation of the propagation properties of these systems. The…

The transverse electromagnetic horn antenna as an efficient THz pulse emitter

Jean-Francois Lampin, Emilien Peytavit, Tahsin Akalin, Guillaume Ducournau, Jens Klier, Sabine Wohnsiedler, Joachim Jonuscheit, René Beigang

We have fabricated a new photoconductive antenna based on a transverse electromagnetic horn and low temperature grown GaAs. It has been tested with a time-domain terahertz setup. The horn was used as the emitter and a standard dipole photoconductive antenna was used as the receiver. The spectrum…

Optimization of carrier multiplication in quantum dots for more efficient solar cells

Christophe Delerue, Guy Allan

Reviewing recent theoretical works, we propose a strategy to optimize the carrier multiplication in semiconductor quantum dots. This strategy is discussed using calculations on quantum dots of a semi-metal, α-Sn.
