A D-Band Passive Receiver with 10 dB Noise Figure for In-situ Noise Characterization in BiCMOS 55 nm

Simon Bouvot, Thomas Quemerais, Joao Carlos Azevedo Goncalves, Sylvie Lepilliet, Guillaume Ducournau, Francois Danneville, Daniel Gloria

A millimeter-wave (mmW) frequency passive mixer for in-situ noise characterization in 110-170 GHz (Dband) is demonstrated using STMicroelectronics BiCMOS 55 nm technology. The circuit uses a gate-pumped MOS transistor with transmission lines filters, without any IF amplifier, allowing a direct...

Nanomaterials for transdermal drug delivery: beyond the state of the art of liposomal structures

Roxana Jijie, Alexandre Barras, Rabah Boukherroub, Sabine Szunerits

A wide range of biomedical materials have been proposed to meet the different needs for controlled oral or intravenous drug delivery. The advantages of oral delivery such as self-administration of a predetermined drug dose at defined time intervals makes it the most convenient means for the...

Coupled model for determination of full electroelastic sets of 1-3 piezocomposite with various pillar shapes

Antoine Bale, Franck Levassort, Anne-Christine Hladky

The knowledge and determination of effective elastic, piezoelectric and dielectric constants for 1-3 piezocomposites play a key role in understanding and optimizing the performance of the material for various applications. This paper details a theoretical coupled method for determining the...

A 140 GHz to 160 GHz active impedance tuner for in-situ noise characterization in BiCMOS 55 nm

Simon Bouvot, Joao Carlos Azevedo Goncalves, Alice Bossuet, Thomas Quemerais, Sylvie Lepilliet, Guillaume Ducournau, Francois Danneville, Daniel Gloria

A millimeter-wave active impedance tuner is implemented on the STMicroelectronics BiCMOS 55 nm technology for in-situ noise characterization. The presented circuit is composed of a two stage low noise amplifier with a gain of 11 dB and a NF of 7.5 dB at 150 GHz loading a 64 states passive impedance...

Visible light assisted hydrogen generation from complete decomposition of hydrous hydrazine using rhodium modified TiO2 photocatalysts

Pawan Kumar, Anurag Kumar, Clemence Queffelec, Dietrich Gudat, Qi Wang, Suman L. Jain, Rabah Boukherroub, Sabine Szunerits

Hydrogen is considered to be an ideal energy carrier, which produces only water when combined with oxygen and thus has no detrimental effect on the environment. While the catalytic decomposition of hydrous hydrazine for the production of hydrogen is well explored, little is known about its...

Acoustic Energy Transfer by Friction Induced Vibrations

Giovanna Lacerra, F. Massi, Eric Chatelet, Emmanuel Moulin

Friction-induced vibrations are often investigated for their unwanted effects, such as surface wear and dynamic instabilities. This article focuses on the exploitation of friction-induced vibrations to transfer the energy between different acoustic fields by an interface under frictional contact....

Minimum Line Width of Surface Plasmon Resonance in Doped ZnO Nanocrystals

Christophe Delerue

The optical response of ZnO nanocrystals (NCs) doped with Al (Ga) impurities is calculated using a model that incorporates the effects of quantum confinement, dielectric mismatch, surface, and ionized impurity scattering. For dopant concentrations of a few percent, the NC polarizability is...

Universal behavior of electron g -factors in semiconductor nanostructures

Athmane Tadjine, Yann-Michel Niquet, Christophe Delerue

We combine analytic developments and numerical tight-binding calculations to study the evolution of the electron g-factors in homogeneous nanostructures of III-V and II-VI semiconductors. We demonstrate that the g-factor can be always written as a sum of bulk and surface terms. The bulk term, the...

Sputtered titanium carbide thick film for high areal energy on chip carbon-based micro-supercapacitors

Manon Létiche, Kevin Brousse, Arnaud Demortiere, Peihua Huang, Barbara Daffos, Sébastien Pinaud, Marc Respaud, Bruno Chaudret, Pascal Roussel, Lionel Buchaillot, Pierre-Louis Taberna, Patrice Simon, Christophe Lethien

The areal energy density of on-chip micro-supercapacitors should be improved in order to obtain autonomous smart miniaturized sensors. To reach this goal, high surface capacitance electrode (>100 mF cm−2) has to be produced while keeping low the footprint area. For carbide-derived carbon (CDC)...
