Role of impact ionization in multiple exciton generation in PbSe nanocrystals

Guy Allan, Christophe Delerue

In the impact ionization process, a hot carrier relaxes by generating an exciton. We present tight binding calculations showing that the rate of this process in PbSe nanocrystals has a strong energy dependence and that the relaxation energy increases linearly with the carrier excess energy. The…

High crosstalk InP digital optical switch for microwave application

Malek Zegaoui, Joseph Harari, D. Lauvernier, Didier Decoster, Jean Chazelas

Because electro-optic switches are key elements for the synthesis of large bandwidth, high dynamic, true time delay optically controlled microwave antennas, we designed, fabricated and characterized a new digital optical switch grown on InP substrate, and based on carrier-induced effects. The…

Study of field plate AlGaN/GaN HEMTs by means of a 2D-hydrodynamic model for power applications

Brahim Benbakhti, Michel Rousseau, Jean-Claude de Jaeger

Field plate AlGaN/GaN HEMT (high electron mobility transistor) structures, are very promising to improve the microwave power performance. This device permits to improve the breakdown voltage but the field plate (FP) electrode involves an increase of the parasitic capacitances and consequently a…
