Gallium nitride MEMS resonators: how residual stress impacts design and performances

Christophe Morelle, Didier Theron, Joff Derluyn, Stefan Degroote, Marianne Germain, Victor Zhang, Lionel Buchaillot, Bertrand Grimbert, Pascal Tilmant, Francois Vaurette, Isabelle Roch-Jeune, Virginie Brandli, Vanessa Avramovic, Etienne Okada, Marc Faucher

Starting from Gallium Nitride epitaxially grown on silicon, pre-stressed micro-resonators with integrated piezoelectric transducers have been designed, fabricated, and characterized. In clamped-clamped beams, it is well known that tensile stress can be used to increase the resonant frequency. Here...

Resolution Improvement Method for Non-Destructive Imaging with Near-Field Scanning Microwave Microscopy

Tianjun Lin, S. Gu, T. Lasri

In this paper we report a resolution enhancement method for non-destructive imaging application with near-field scanning microwave microscopy (NFMM). The technique proposed for the image processing is based on the combination of the position/signal difference (PSD) method and an adaptive robust...

Spatiotemporal control of DNA-based chemical reaction network via electrochemical activation in microfluidics

Ievgen Kurylo, Guillaume Gines, Yannick Rondelez, Yannick Coffinier, Alexis Vlandas

In recent years, DNA computing frameworks have been developed to create dynamical systems which can be used for information processing. These emerging synthetic biochemistry tools can be leveraged to gain a better understanding of fundamental biology but can also be implemented in biosensors and...

Semi-analytical discontinuous Galerkin finite element method for the calculation of dispersion properties of guided waves in plates

Salah-Eddine Hebaz, Farouk Benmeddour, Emmanuel Moulin, Jamal Assaad

The development of reliable guided waves inspection systems is conditioned by an accurate knowledge of their dispersive properties. The semi-analytical finite element method has been proven to be very practical for modeling wave propagation in arbitrary cross-section waveguides. However, when it...

Spacetime representation of topological phononics

Pierre A. Deymier, Keith Runge, Pierre Lucas, Jerome O. Vasseur

Non-conventional topology of elastic waves arises from breaking symmetry of phononic structures either intrinsically through internal resonances or extrinsically via application of external stimuli. We develop a spacetime representation based on twistor theory of an intrinsic topological elastic...

Optimization of pentacene double floating gate memories based on charge injection regulated by SAM functionalization

S. Li, David Guérin, Stéphane Lenfant, K. Lmimouni

Pentacene based double nano-floating gate memories (NFGM) by using gold nanoparticles (Au NPs) and reduced graphene oxide (rGO) sheets as charge trapping layers are prepared and demonstrated. Particularly, the NFGM chemically treated by 2,3,4,5,6-pentafluorobenzenethiol (PFBT) self-assembled...

Ultra-low loss ridge waveguides on lithium niobate via argon ion milling and gas clustered ion beam smoothening

Shawn Yohanes Siew, Eric Jun Hao Cheung, Haidong Liang, Andrew Bettiol, Noriaki Toyoda, Bandar Alshehri, El Hadj Dogheche, Aaron J. Danner

Lithium niobate's use in integrated optics is somewhat hampered by the lack of a capability to create low loss waveguides with strong lateral index confinement. Thin film single crystal lithium niobate is a promising platform for future applications in integrated optics due to the availability...

Strain-Reduction Induced Rise in Channel Temperature at Ohmic Contacts of GaN HEMTs

Steven Duffy, Brahim Benbakhti, Karol Kalna, Mohammed Boucherta, Wei Zhang, Nour Eddine Bourzgui, Ali Soltani

ABSTRACT Operating temperature distributions in AlGaN/GaN gateless and gated devices are characterized and analyzed using the InfraScope temperature mapping system. For the first time, a substantial rise of channel temperature at the inner ends of ohmic contacts has been observed. Synchrotron...
