Fully relaxed low-mismatched InAlAs layer on an InP substrate by using a two step buffer

S.R. Plissard, Christophe Coinon, Ydir Androussi, X. Wallart

The strain relaxation in low mismatched InxAl1−xAs layers has been studied by triple axis x-ray diffraction, transmission electron microscopy, and photoluminescence. Using a two step buffer, a fully relaxed top layer has been grown by adapting the composition and thickness of a first “strained...

Doped graphene as tunable electron-phonon coupling material

Claudio Attaccalite, L. Wirtz, M. Lazzeri, Francesco Mauri, A. Rubio

We present a new way to tune the electron-phonon coupling (EPC) in graphene by changing the deformation potential with electron/hole doping. We show the EPC for highest optical branch at the high symmetry point K, acquires a strong dependency on the doping level due to electronelectron correlation...

Analysis of a narrowband terahertz signal generated by a unitravelling carrier photodiode coupled with a dual-mode semiconductor Fabry-Pérot laser

Sylwester Latkowski, Josué Parra-Cetina, Ramon Maldonado-Basilio, Pascal Landais, Guillaume Ducournau, Alexandre Beck, Emilien Peytavit, Tahsin Akalin, Jean-Francois Lampin

A narrowband terahertz signal generated by a unitravelling carrier photodiode (UTC-PD) interfaced with a dual-mode Fabry–Pérot laser diode is demonstrated. A beat tone corresponding to the free spectral range is generated on the UTC-PD, and radiated by a transverse-electromagnetic-horn antenna. A...

Above-barrier surface electron resonances induced by a molecular network

Rares Stiufiuc, Luis Perdigao, B. Grandidier, D. Deresmes, Guy Allan, Christophe Delerue, Didier Stiévenard, Peter Beton, Steven Erwin, Michel Sassi, Vincent Oison, Jean-Marc Debierre

We report the modification of the density of states of the Ag/Si(111)−√3×√3R30° surface by a self-assembled molecular network at energies much higher than the height of the potential barriers induced by the molecules. Map of the differential conductance obtained by scanning tunneling spectroscopy...

ZnO contour-mode resonator

Tadeusz Gryba, Julien Carlier, Shengxiang Wang, Xingzhong Zhao, Shishang Guo, Jean-Etienne Lefebvre

This paper reports on design, fabrication and experimental testing of one port ZnO piezoelectric contour- mode MEMS resonator. This is a rectangular plate formed by ZnO layer between two electrodes platinum and aluminium. A vertical electric field is applied to a layer of ZnO and induces in plane...
