Interface engineering for improved light transmittance through photonic crystal flat lenses

Geoffroy Scherrer, Maxence Hofman, Wojciech Smigaj, B. Gralak, X. Melique, O. Vanbesien, D. Lippens, Colette Dumas, Benoît Cluzel, F. de Fornel

In this paper, we present photonic crystal flat lenses with interfaces engineered to improve the light transmittance thanks to a broad angles impedance matching. The interface engineering consists in the realization of antireflection gratings on the edges of the lenses which are designed to reduce…

High on-off conductance switching ratio in optically-driven self-assembled conjugated molecular systems

K. Smaali, S. Lenfant, S. Karpe, M. Oçafrain, P. Blanchard, D. Deresmes, S. Godey, A. Rochefort, J. Roncali, D. Vuillaume

A new azobenzene-thiophene molecular switch is designed, synthesized and used to form self-assembled monolayers (SAM) on gold. An "on/off" conductance ratio up to 7x103 (with an average value of 1.5x103) is reported. The "on" conductance state is clearly identified to the cis…

Graphene growth by molecular beam epitaxy using a solid carbon source

E. Moreau, F.J. Ferrer, D. Vignaud, S. Godey, X. Wallart

The direct elaboration of graphene by molecular beam epitaxy (MBE) has been studied, using a solid carbon source. Successful growth has been achieved on both the carbon and silicon terminated faces of silicon carbide substrates in the temperature range 1000-1100 °C, as confirmed by low energy…
