Equivalent circuit model of a nanogenerator based on a piezoelectric nanowire-polymer composite

Autor: Olivier Graton, Louis-Pascal Tran Huu Hue, Marc Lethiecq, Nicolas Camara, Abhishek Singh Dahiya, Guylaine Poulin-Vittrant

Publikováno v: physica status solidi (RRL) - Rapid Research Letters. 7:915-918

A vertically integrated nanogenerator (VING) refers to the new generation of mechanical energy harvesting devices: arrays of piezoelectric and semiconducting nanowires are grown perpendicularly to a substrate and appropriate electrodes enable charge

Canonical Quantization of the Boundary Wess-Zumino-Witten Model

Autor: Krzysztof Gawedzki, Ivan Todorov, Pascal Tran-Ngoc-Bich

Publikováno v: Communications in Mathematical Physics. 248:217-254

We present an analysis of the canonical structure of the WZW theory with untwisted conformal boundary conditions. The phase space of the boundary theory on a strip is shown to coincide with the phase space of the Chern-Simons theory on a solid cylind

Electroacoustic modeling and characterization of an ultrasonic projector

Autor: Guy Feuillard, Jean Francois Saillant, Pascal Tran Huu Hue, Marc Lethiecq, Van Thien Nguyen, Naoufal Saadaoui

Publikováno v: The Journal of the Acoustical Society of America. 142:2547-2547

Ultrasonic projectors are new type ultrasonic transducers that take advantage of the ultrasonic wave emitted on the rear face of the transducer. It consist in an acoustic symmetrical design where both waves generated on the faces of the piezoelectric

Controlled Growth of 1D and 2D ZnO Nanostructures on 4H-SiC Using Au Catalyst

Autor: Olivier Graton, Frédéric Cayrel, Louis-Pascal Tran Huu Hue, Nicolas Camara, Abhishek Singh Dahiya, Guylaine Poulin-Vittrant, Daniel Alquier, Charles Opoku

Publikováno v: Nanoscale Research Letters
Nanoscale Research Letters, 2014, 9 (1), pp.379. ⟨10.1186/1556-276X-9-379⟩

A perfect control of nanostructure growth is a prerequisite for the development of electronic and optoelectronic device/systems. In this article, we demonstrate the growth of various ZnO-derived nanostructures, including well-ordered arrays of high a

High-frequency and high-temperature electromechanical performances of new PZT–PNN piezoceramics

Autor: Marc Lethiecq, Erling Ringaard, Pascal Tran-Huu-Hue, Franck Levassort

Publikováno v: Journal of the European Ceramic Society. 21:1361-1365

Ferroelectric ceramics based on a solid solution between a PZT ferroelectric phase and a relaxor phase from the lead–nickel–niobium system are characterised. Two different mixed-oxide routes have been used in order to compare the dielectric, piez

Preparation and electromechanical properties of PZT/PGO thick films on alumina substrate

Autor: Marc Lethiecq, François Vander Meulen, Marija Kosec, Pascal Tran-Huu-Hue, Janez Holc, Franck Levassort

Publikováno v: Journal of the European Ceramic Society. 21:1445-1449

PZT thick films with lead germanate as low temperature sintering aid were prepared on alumina substrates. The thickness of films after sintering procedures reached 50 μm. Chemical compatibility and microstructure of layers was studied by EDS/SEM ana
