100nm AlSb/InAs HEMT for ultra-low-power consumption, low-noise applications

Cyrille Gardès, Sonia Bagumako, L. Desplanque, Nicolas Wichmann, S. Bollaert, Francois Danneville, Xavier Wallart, Yannick Roelens

We report on high frequency (HF) and noise performances of AlSb/InAs high electron mobility transistor (HEMT) with 100 nm gate length at room temperature in low-power regime. Extrinsic cut-off frequencies of 100/125 GHz together with minimum noise figure dB and associated gain dB at 12 GHz have…

A one-dimensional optomechanical crystal with a complete phononic band gap

J. Gomis-Bresco, D. Navarro-Urrios, M. Oudich, Said El-Jallal, A. Griol, D. Puerto, E. Chavez, Yan Pennec, Bahram Djafari-Rouhani, F. Alzina, A. Martínez, C.M. Sotomayor Torres

Recent years have witnessed the boom of cavity optomechanics, which exploits the confinement and coupling of optical and mechanical waves at the nanoscale. Among their physical implementations, optomechanical (OM) crystals built on semiconductor slabs enable the integration and manipulation of…

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…

On the correlation between kink effect and effective mobility in InAlN/GaN HEMTs

Philippe Altuntas, N. Defrance, Marie Lesecq, Alain Agboton, Rezki Ouhachi, Etienne Okada, Christophe Gaquière, Jean-Claude de Jaeger, Éric Frayssinet, Yvon Cordier

This paper reports on the kink effect observed in InAlN/GaN high electron mobility transistors. Electrical characterizations were carried out to point out the influence of this phenomenon on transistor behaviour. It is demonstrated that the kink effect is directly correlated to shallow traps…

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…

Insulin loaded iron magnetic nanoparticle–graphene oxide composites: synthesis, characterization and application for in vivo delivery of insulin

Kostiantyn Turcheniuk, Manakamana Khanal, Anastasiia Motorina, Palaniappan Subramanian, Alexandre Barras, Vladimir Zaitsev, Victor Kuncser, Aurel Leca, Alain Martoriati, Katia Cailliau-Maggio, Jean-Francois Bodart, Rabah Boukherroub, Sabine Szunerits

One of the focal subjects in insulin delivery is the development of insulin formulations that protect the native insulin from degradation under acidic pH in the stomach. In this work we show, for the first time, that a graphene oxide (GO) based matrix can ensure the stability of insulin at low pH.…
