Evaluation of a gate capacitance in the sub-aF range for a chemical field-effect transistor with a silicon nanowire channel

N. Clement, K. Nishiguchi, A. Fujiwara, D. Vuillaume

An evaluation of the gate capacitance of a fieldeffect transitor (FET) whose channel length and width are several ten nanometer, is a key point for sensors applications. However, experimental and precise evaluation of capacitance in the aF range or less has been extremely difficult. Here, we report…

Large array of sub-10-nm single-grain Au nanodots for use in nanotechnology

N. Clement, G. Patriarche, K. Smaali, Francois Vaurette, K. Nishiguchi, David Troadec, A. Fujiwara, D. Vuillaume

A uniform array of single-grain Au nanodots, as small as 5-8 nm, can be formed on silicon using e-beam lithography. The as-fabricated nanodots are amorphous, and thermal annealing converts them to pure Au single crystals covered with a thin SiO2 layer. These findings are based on physical…

Contact angle hysteresis origins: investigation on super-omniphobic surfaces

Renaud Dufour, Maxime Harnois, Vincent Thomy, Rabah Boukherroub, Vincent Senez

Contact angle hysteresis of liquid droplets is investigated on sticky and flexible super-omniphobic surfaces made up of PDMS–Si3N4 microstructures. Up to now, extensive studies have been focusing on the relation between hysteresis and surface properties such as roughness or defect density. However…

Dispersion of confined acoustic phonons in ultra-thin Si membranes

J. Cuffe, E. Chavez, P.O. Chapuis, E.H. El Boudouti, F. Alzina, D. Dudek, Yan Pennec, Bahram Djafari-Rouhani, A. Shchepetov, M. Prunnila, J. Ahopelto, C.M. Sotomayor Torres

The acoustic phonon dispersion curves of ~10 and ~30 nm Si membranes were measured using Brillouin Light Scattering (BLS) spectroscopy. The dispersion relations of the confined phonons were calculated from a semi-analytical model based on continuum elasticity theory. Green’s function simulations…
