Enhancement of thermoelectric power factor in NaxCoO2/Au multilayers

Xiaohui Zhao, Haifeng Wang, Shufang Wang, El Hadj Dogheche, Jianglong Wang, Guangsheng Fu

NaxCoO2/Au thin film multilayers, with a thickness of the Au layer of 0.5–12 nm, have been fabricated on c-Al2O3 by post annealing of the CoO/Au thin film multilayers in Na vapor at high temperature in air. X-ray diffraction measurements revealed that the resulting NaxCoO2 layer was c-axis oriented…

Millimeter-wave in situ tuner : an efficient solution to extract the noise parameters of SiGe HBTs in the whole 130-170 GHz range

Marina Deng, Laurent Poulain, Daniel Gloria, Thomas Quémerais, Pascal Chevalier, Sylvie Lepilliet, Francois Danneville, Gilles Dambrine

SiGe HBT noise parameters ( , and ) are for the first time extracted in the entire 130 - 170 GHz frequency range. This achievement is realized using a D-band on-chip source-pull system, which includes an impedance tuner integrated with the transistor under test. On-wafer noise power measurements on…

Joint estimation of state and noise parameters in a linear dynamic system with impulsive measurement noise: Application to OFDM systems

Nouha Jaoua, Emmanuel Duflos, Philippe Vanheeghe, Laurent Clavier, François Septier

Interference mitigation is one of the main challenges in wireless communication, especially in ad hoc networks. In such context, the Multiple Access Interference (MAI) is known to be of an impulsive nature. Therefore, the conventional Gaussian assumption is inadequate to model this type of…

Electro-optic and converse-piezoelectric properties of epitaxial GaN grown on silicon by metal-organic chemical vapor deposition

Mireille Cuniot-Ponsard, Irma Saraswati, S.M. Ko, Mathieu Halbwax, Y.H. Cho, El Hadj Dogheche

We report the measurement of the (r13, r33) Pockels electro-optic coefficients in a GaN thin film grown on a Si(111) substrate. The converse piezoelectric (d33) and electro-absorptive coefficients are simultaneously determined. Single crystalline GaN epitaxial layers were grown with a AlGaN buffer…

Sub-THz characterisation of multi-walled carbon nanotube thin films using vector network analyser

S. Puthukodan, E. Dadrasnia, V.K.T. Vinod, H.K. Nguendon, H. Lamela, Guillaume Ducournau, Jean-Francois Lampin, F. Garet, J.L. Coutaz, D.M. Lee, S. Baik

A vector network analyser is used to study the electrical properties of multi-walled carbon nanotube (MWCNT) thin films deposited on a fused quartz substrate in the sub-terahertz (THz) frequency ranges of 220-325 GHz (WR3.4) and 325-500 GHz (WR2.2). The experiment is performed in free space. The…

Influence of an interfacial AlxIn1-xSb layer on the strain relaxation and surface morphology of thin GaSb layers epitaxially grown on GaAs(001)

Mathieu Danoy, Pierre-François Angry, Julien Gavrel, Charlène Brillard, L. Desplanque, Y. Wang, P. Ruterana, Xavier Wallart

This work focuses on the strain relaxation and surface morphology of 10 ML thick GaSb layers on GaAs. It is shown that full relaxation is never reached for this thickness. The use of an AlSb interfacial layer only slightly improves strain relaxation but greatly reduces surface roughness. Finally,…
