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…

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…

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…

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…

Adjustable supercontinuum laser source with low coherence length and low timing jitter

Marco Andreana, Anne Bertrand, Y. Hernandez, Philippe Leproux, Vincent Couderc, Stéphane Hilaire, Guillaume Huss, D. Giannone, Alessandro Tonello, Alexis Labruyère

This paper introduces a supercontinuum (SC) laser source emitting from 400 nm to beyond 1750 nm, with adjustable pulse repetition rate (from 250 kHz to 1 MHz) and duration (from ~200 ps to ~2 ns). This device makes use of an internally-modulated 1.06 μm semiconductor laser diode as pump source. The…

Characterization of nano-crystalline diamond films grown under continuous DC bias during plasma enhanced chemical vapor deposition

V. Mortet, L. Zhang, M. Eckert, A. Soltani, J. d'Haen, O. Douhéret, M. Moreau, S. Osswald, E. Neyts, David Troadec, P. Wagner, A. Bogaerts, G. van Tendeloo, K. Haenen

Nanocrystalline diamond films have generated much interested due to their diamond-like properties and low surface roughness. Several techniques have been used to obtain a high re-nucleation rate, such as hydrogen poor or high methane concentration plasmas. In this work, the properties of nano-…

Sub-Terahertz imaging with AlGaN/GaN MISFETs

Salman Nadar, Oleg Klimenko, Hadley Videlier, Dominique Coquillat, Nina Diakonova, Frederic Teppe, Wojciech Knap, K. Madjour, Guillaume Ducournau, Christophe Gaquière, M. A. Poisson, J. Torres, J. Szczytko, A. Dobroiu, C. Otani

We evaluate the optical performance of AlGaN/GaN MISFETs as a non-resonant sub-terahertz, room temperature detector. The single-pixel responsivity and the noise equivalent power are determined. The efficiency of the detection is demonstrated by the room temperature imaging of different solutions of…
