Applicability of acoustic noise correlation for structural health monitoring in nondiffuse field conditions

Emmanuel Moulin, Najib Abou Leyla, Jamal Assaad, Sébastien Grondel

Ambient noise correlation offers an elegant way of passively caracterize a medium. The principle is that in diffuse field condition, Green’s function between two sensors can be retrieved from the cross-correlated received signals. Here, the technique is applied in conditions where convergence...

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...
