GaN high electron mobility transistors on silicon substrates with MBE/PVD AlN seed layers

Yvon Cordier, Éric Frayssinet, Magdalena Chmielowska, Maud Nemoz, Aimeric Courville, Philippe Vennéguès, P. de Mierry, Sebastien Chenot, Julien Camus, Keltouma Aït Aïssa, Quentin Simon, Laurent Le Brizoual, Mohamed Abdou Djouadi, N. Defrance, Marie Lesecq, Philippe Altuntas, Adrien Cutivet, Alain Agboton, Jean-Claude de Jaeger

In the present paper, we describe the development of new AlN seed layers obtained by combining molecular beam epitaxy and low temperature physical vapour deposition (magnetron sputtering). It is shown that it is possible to grow thick AlN seed layers with a good in-plane crystal ordering. GaN based…

Tailoring thermal conductivity of graphene via defect-and-molecular engineering

Stefan Bringuier, J.F. Robillard, Pierre Deymier, Krishna Muralidharan

The exceptional thermal properties of graphene have attracted enormous interest over the past decade. Consequently, there is an increased push towards utilizing graphene in thermal-management systems such as thermal interface materials and thermoelectrics. While, many recent investigations have…

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…

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…

Comparison of shallow-mesa InAs/AlSb HEMTs with and without early-protection for long-term stability against Al(Ga)Sb oxidation

E. Lefebvre, G. Moschetti, M. Malmkvist, L. Desplanque, X. Wallart, J. Grahn

The fabrication process of InAs/AlSb high electron mobility transistors (HEMTs) has been improved by depositing, after the shallow-mesa isolation of the active area, a thin SiNx-film on the exposed AlGaSb mesa floor. Devices with and without this early-protection against Al(Ga)Sb oxidation have…
