Limitations of the impulse response of GaAs MSM photoswitch

Sabah Benzeghda, Farida Hobar, Didier Decoster, Jean-Francois Lampin

As symmetrical data characteristics I (V) of the Metal-Semiconductor-Metal (MSM) photodetector, we wondered how this device can be used as a photoswitch as well as the low temperature on GaAs photoconductive generally used for this purpose. The impulse response of interdigitated metal-semiconductor…

Electrical method for crosstalk cancellation in transducer arrays

Abdelmajid Bybi, Christian Granger, Sébastien Grondel, Anne-Christine Hladky, Jamal Assaad

In this paper, we report a new and simple electrical method to cancel crosstalk in the acoustical arrays. This solution has several advantages compared with that proposed in a previous paper (Bybi et al 2013) [17] where adapted electrical voltages were applied to each neighboring element of the…

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…

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…

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…

Miniaturized Microcantilever-based RF Microwave Probes Using MEMS Technologies

Jaouad Marzouk, S. Arscott, Kamel Haddadi, Tuami Lasri, Christophe Boyaval, Sylvie Lepilliet, Gilles Dambrine

In this study, miniaturized microwave cantilever-based probes - using silicon-on-insulator (SOI) technology - are proposed for the on-chip electrical characterization of nanodevices. In contrast with conventional on-wafer probing structures, small pad dimensions around 1 μm2 associated with a 4.5…

A study on effect of wafer bow in wafer-level BCB cap transfer packaging

Seonho Seok, Janggil Kim

This paper investigates the effects of wafer bow of Si carrier wafer to achieve high-yield BCB cap transfer in wafer-scale packaging. BCB caps are built-up on Si carrier wafer and then they are bonded and transferred to a target wafer. The height of BCB cap is 25 lm and the thickness of Si carrier…

Gold-free ternary III-V antimonide nanowire arrays on silicon : twin-free down to the first bilayer

Sònia Conesa-Boj, Dominik Kriegner, Xiang-Lei Han, S.R. Plissard, Xavier Wallart, Julian Stangl, Anna Fontcuberta I Morral, Philippe Caroff

With the continued maturation of III-V nanowire research, expectations of material quality should be concomitantly raised. Ideally, III-V nanowires integrated on silicon should be entirely free of extended planar defects such as twins, stacking faults, or polytypism, position-controlled for…
