Ultrafast acoustics in the middle UV range: coherent phonons at higher frequencies and in smaller objects

S. Ayrinhac, Arnaud Devos, A. Le Louarn, P.-A. Mante, P. Emery

We show that the propagation of coherent acoustic phonons generated by femtosecond optical excitation can be clearly resolved using a probe laser in the middle UV (MUV) range. The MUV probe is easily produced from a highrepetition- rate femtosecond laser and a homemade frequency tripler. We present...

Graphene growth by molecular beam epitaxy on the carbon-face of SiC

E. Moreau, S. Godey, F.J. Ferrer, D. Vignaud, X. Wallart, J. Avila, M.C. Asensio, F. Bournel, J.J. Gallet

Graphene layers have been grown by molecular beam epitaxy (MBE) on the (0001¯) C-face of SiC and have been characterized by atomic force microscopy, low energy electron diffraction (LEED), and UV photoelectron spectroscopy. Contrary to the graphitization process, the step-terrace structure of SiC...

Microwave modulation of terahertz quantum cascade lasers : a transmission-line approach

Wilfried Maineult, Lu Ding, Pierre Gellie, Pascal Filloux, Carlo Sirtori, Stefano Barbieri, Tahsin Akalin, Jean-Francois Lampin, Isabelle Sagnes, Harvey E. Beere, David Ritchie

We report on microwave impedance measurements of metal-metal ridge-waveguide terahertz quantum cascade lasers. Experimental data, recorded at 4 K in the 100 MHz–55 GHz range, are well reproduced by distributed-parameter transmission-line simulations, showing that the modulation cutoff is limited by...

A three-dimensional Monte Carlo model for the simulation of nanoelectronic devices

T. Sadi, Jean-Luc Thobel

We present a three-dimensional (3D) semi-classical ensemble Monte Carlo model newly developed to simulate a variety of nanoelectronic devices. The characteristics of the 3D model are compared with the widely used two-dimensional (2D) models. The advantages of our model, in terms of accuracy in...
