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…

Nanowire biocompatibility in the brain - Looking for a needle in a 3D stack

Cecilia Eriksson-Linsmeier, Christelle Prinz, Lina M. E. Pettersson, Philippe Caroff, Lars Samuelson, Jens Schouenborg, Lars Montelius, Nils Danielsen

We investigated the brain-tissue response to nanowire implantations in the rat striatum after 1, 6, and 12 weeks using immunohistochemistry. The nanowires could be visualized in the scar by confocal microscopy (through the scattered laser light). For the nanowire-implanted animals, there is a…

Determination of the electrostatic lever arm of carbon nanotube field effect transistors using Kelvin force microscopy

David Brunel, D. Deresmes, Thierry Melin

We use Kelvin force microscopy (KFM) to study the electrostatic properties of single-walled carbon nanotube field effect transistor devices (CNTFETs) with backgate geometry at room temperature. We show that KFM maps recorded as a function of the device backgate polarization enable a complete…
