First AlN/GaN HEMTs power measurement at 18 GHz on silicon substrate

F Medjdoub, Malek Zegaoui, Damien Ducatteau, N. Rolland, Paul-Alain Rolland

AlN/GaN heterostructure is an ideal candidate to push the limits of microwave GaN-based devices owing to the maximum theoretical spontaneous and piezoelectric difference between the epitaxial AlN barrier and the underlying GaN layer. If the tricky growth conditions of this binary can be controlled...

Beyond 100 GHz AlN/GaN HEMTs on silicon substrate

F Medjdoub, Malek Zegaoui, N. Rolland

A report is presented on high-speed 100nm AlN/GaN high-electron-mobility transistors (HEMTs) grown on (111) high-resistive silicon substrate. The device delivers an extrinsic peak transconductance gm=530mS/mm, a maximum current of 1.74A/mm, and current gain and maximum oscillation cutoff...

Controlling gigahertz and terahertz surface electromagnetic waves with metamaterial resonators

Wenchen Chen, J.J. Mock, D.R. Smith, Tahsin Akalin, Willie J. Padilla

We computationally and experimentally investigate the use of metamaterial resonators as bandpass filters and other components that enable control of guided surface electromagnetic waves. The guided surface electromagnetic wave propagates on a planar Goubau line, launched via a coplanar waveguide...

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

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...
