Synthesis of long group IV semiconductor nanowires by molecular beam epitaxy

T. Xu, J. Sulerzycki, J.P. Nys, G. Patriarche, B. Grandidier, D. Stievenard

We report the growth of Si and Ge nanowires (NWs) on a Si(111) surface by molecular beam epitaxy. While Si NWs grow perpendicular to the surface, two types of growth axes are found for the Ge NWs. Structural studies of both types of NWs performed with electron microscopies reveal a marked…

Band offsets, wells, and barriers at nanoscale semiconductor heterojunctions

Y.M. Niquet, C. Delerue

Epitaxially grown semiconductor heterostructures make it possible to tailor the potential landscape for the carriers in a very controlled way. In planar lattice-matched heterostructures, the potential has indeed a very simple and easily predictable behavior: it is constant everywhere except at the…

Strain relief at the GaSb/GaAs interface versus substrate surface treatment and AlSb interlayer thickness

Y. Wang, P. Ruterana, L. Desplanque, S. El Kazzi, X. Wallart

Using transmission electron microscopy we investigate the influence of AlSb monolayers and substrate surface preparation on the microstructure of GaSb grown on GaAs (001) by molecular beam epitaxy. The geometric phase analysis method is used to analyze the interface dislocation type and the…

One port contour-mode ZnO piezoelectric MEMS resonator

Tadeusz Gryba, Julien Carlier, S.X. Wang, X.Z. Zhao, S. Guo, Jean-Etienne Lefebvre

This paper reports on design, fabrication and experimental testing of one port ZnO contour-mode resonant MEMS. The devices are fabricated from silicon wafers using a 4-mask process. The use of contour modes, whose frequencies are set by lithographically defined dimensions, permits the fabrication…

Magnonic circuits and crystals

Housni Al-Wahsh, Abdellatif Akjouj, Bahram Djafari-Rouhani, L. Dobrzynski

In the frame of the long-wavelength Heisenberg model, a simple magnonic mono-mode circuit is designed to obtain transmission stop (pass) bands where the propagation of spin waves is forbidden (allowed). This simple device is composed of an infinite one-dimensional monomode waveguide (the backbone)…

Highly coherent terahertz wave generation with a dual-frequency Brillouin fiber laser and a 1.55 μm photomixer

Guillaume Ducournau, P. Szriftgiser, Tahsin Akalin, Alexandre Beck, Denis Bacquet, Emilien Peytavit, Jean-Francois Lampin

Thanks to a portable dual-frequency Brillouin fiber laser and a 1.55 μm photomixer, we report the generation of a highly coherent kilohertz level submillimeter wave emission. Low-cost telecommunications components are used to achieve very simple source architecture. The photomixer is composed of a…
