Ultrafast electron-phonon decoupling in graphite

K. Ishioka, M. Hase, M. Kitajima, L. Wirtz, A. Rubio, H. Petek

We report the ultrafast dynamics of the 47.4 THz coherent phonons of graphite interacting with a photoinduced non-equilibrium electron-hole plasma. Unlike conventional materials, upon photoexcitation the phonon frequency of graphite upshifts, and within a few picoseconds relaxes to the stationary...

Monte Carlo modeling of carrier-carrier scattering in semiconductors with nonparabolic bands

Olivier Bonno, Jean-Luc Thobel

An efficient algorithm to account for nonparabolicity in carrier-carrier scattering in an ensemble Monte Carlo simulator is proposed. The major difficulty of modeling intercarrier scattering in semiconductors with nonparabolic bands arises from the two particle momentum and energy conservation laws...

Piezoelectric response of PZT nanostructures obtained by focused ion beam

Denis Remiens, Liang Ruihong, David Troadec, D. Deresmes, Caroline Soyer, Antonio Da Costa, Rachel Desfeux

Pb(Zrx,Ti1 - x)O3 (PZT) microscale island (1μm∼ 100nm) was fabricated by Focused Ion Beam (FIB) before and after its crystallization. In the first case the FIB etching is realized on amorphous films and a post annealing treatment, at the crystallization temperature of the PZT films, is necessary to...

Estimation of dynamic parameters of overthreshold parametric phase conjugation of ultrasound in magnetostrictive ferrites according to data of quasi-static measurements

Andrey Brysev, Philippe Pernod, Vladimir L. Preobrazhensky

A simple method for testing ferrite samples intended to be active elements of parametric phase conjugator of ultrasound was proposed and experimentally approved. The method allows one to estimate such dynamic parameters of parametric phase conjugator of ultrasound as the parametric amplification...
