Terahertz radiation from heavy-ion-irradiated In$_{0.53}Ga_{0.47}$As photoconductive antenna excited at 1.55 $\mu$m

N. Chimot, J. Mangeney, L. Joulaud, P. Crozat, H. Bernas, K. Blary, J. F. Lampin

We investigate terahertz (THz) emission from heavy-ion-irradiated In0.53Ga0.47As photoconductive antennas excited at 1550 nm. The carrier lifetime in the highly irradiated In0.53Ga0.47As layer is less than 200 fs, the steady-state mobility is 490 cm2 V–1 s–1, and the dark resistivity is 3 Omega cm...

Friction driven micromotors with both clockwise and counterclockwise rotations

Bernard Legrand, Lionel Buchaillot, Dominique Collard

This submission presents friction driven angular micro-motors that demonstrate both clockwise (CW) and counter clockwise (CCW) rotations with a single set of mechanical converters. Fabrication technology is based on surface micromachining of polycrystalline silicon layers in thin films. Rotor...

Left-handed electromagnetism via nanostructures materials : comparison to microstructured photonic crystals

M. Perrin, S. Fasquel, T. Decoopman, X. Melique, O. Vanbesien, Eric Lheurette, D. Lippens

In this work, we review some of the key issues for designing dielectric and metallic arrays in the diffraction or refraction regimes with main emphasis on left-handed electromagnetism. We first discuss dispersion characteristics of periodic dielectric arrays which are structured on the wavelength...

Study of structural and optical properties of InSb-doped SiO₂ thin films

B. Capoen, V.Q. Lam, S. Turrell, Jean-Pierre Vilcot, F. Beclin, Y. Jestin, M. Bouazaoui

The non-linear absorption and the structure of rf-cosputtered SiO2:InSb films were investigated after different heat-treatments at temperatures ranging from 200 to 900 °C. The heat-treatment was 1 min or 4 h in an atmosphere of nitrogen or under vacuum, respectively. After annealing at a...

Reactive ion etching of a 20 nanometers tungsten gate using a SF$_6$/N$_2$ chemistry and hydrogen silsesquioxane hard mask resist

G. Larrieu, Emmanuel Dubois

This article reports on a direct method for patterning a tungsten gate in the decananometric range using high-resolution electron-beam lithography and reactive ion etching (RIE). Electron-beam lithography is based on the use of hydrogen silsesquioxane for its remarkable properties as a negative-...
