Epitaxial hexagonal boron nitride on Ir(111) : a work function template

Fabian Schulz, Robert Drost, Sampsa K. Hämäläinen, Thomas Demonchaux, Ari P. Seitsonen, Peter Liljeroth

Hexagonal boron nitride (h-BN) is a prominent member in the growing family of two-dimensional materials with potential applications ranging from being an atomically smooth support for other two-dimensional materials to templating growth of molecular layers. We have studied the structure of...

A GaN Schottky diode-based analog phase shifter MMIC

Chong Jin, Etienne Okada, Marc Faucher, Damien Ducatteau, Mohammed Zaknoune, Dimitris Pavlidis

A GaN Schottky Diode-based Analog Phase Shifter MMIC of T-topology has been designed for 35 GHz operation. An all E-Beam technology was employed for MMIC realization. The measured, as well modeled small and large-signal diode characteristics were used for evaluating the phase-shifter performance in...

Experimental investigation of the characteristics of the electromagnetic reverberation in the UWB bands

Aliou Bamba, Wout Joseph, Emmeric Tanghe, Luc Martens, Davy Gaillot, M. Lienard, Jose-Maria Molina-Garcia-Pardo, Maria-Teresa Martinez-Ingles

The electromagnetic reverberation time characteristics are investigated at UltraWide Band (UWB) frequencies, i.e., from 2 to 10 GHz. The reverberation time is bandwidth independent and decreases as the frequency increases. Besides, the reverberation ratio - the contribution of the diffuse fields in...

Thermoelectric infrared microsensors based on a periodically suspended thermopile integrating nanostructured Ge/SiGe quantum dots superlattice

Katir Ziouche, G. Savelli, Zahia Bougrioua, D. Hauser, P. Lejeune, P.M. Michon, Tuami Lasri, Didier Leclercq

This paper presents an original integration of polycrystalline SiGe-based quantum dots superlattices (QDSL) into Thermoelectric (TE) planar infrared microsensors (μSIR) fabricated using a CMOS technology. The nanostructuration in QDSL results into a considerably reduced thermal conductivity by a...

Inkjet printed flexible transmission lines for high frequency applications up to 67 GHz

Mohamed Moez Belhaj, Wei Wei, Emiliano Pallecchi, Colin Mismer, Isabelle Roch-Jeune, Henri Happy

This letter introduces radio frequency(RF) characterization of ink-jet printed coplanar waveguides (CPW) with and without strain. Kapton is selected as flexible substrate with different sintering temperature. With optimized inkjet printing parameters, well defined patterns with high resolution...
