Fast relaxation of hot carriers by impact ionization in semiconductor nanocrystals : role of defects

Guy Allan, Christophe Delerue

We present calculations predicting that defects at the surface of semiconductor nanocrystals have a strong influence on the dynamics of hot carriers after photoexcitation. The relaxation of excited carriers by impact ionization of carriers trapped on deep levels is efficient, in particular in the…

Electron transport properties of gallium nitride for microscopic power device modelling

Brahim Benbakhti, Michel Rousseau, Ali Soltani, Jean-Claude de Jaeger

The design of power GaN devices has to take into account the impact of temperature on device materials due to highly dissipated power and a consequent large self-heating. The accurate knowledge of transport properties as a function of the lattice temperature is essential in order to make a good…

Channel estimation of OFDM system for high data rate communications on mobile environments

Boudali Ouarzazi, Marion Berbineau, Iyad Dayoub, Atika Rivenq

One of the main challenges of the 4th generation wireless systems is to provide high data rates in mobile environments. In these 4G products, WiMax (worldwide interoperability for microwave access) and LTE (long term evolution) will be the platform technologies. The rapid development of the…

Enhanced performances of MIMO transmissions over correlated channels system by using adaptive bit and power allocation on eigenmodes

Imade Fatani, Mohamed Gharbi, Marie Zwingelstein, Patrick Corlay, Marion Berbineau, François-Xavier Coudoux

In this paper, we propose the use of bit and power allocation procedure to optimize the use of eigenmodes for multiple antenna systems. We design an adaptive algorithm that exploit the Channel State Information (CSI) available at the transmitter by adapting the transmitted signals in order to…
