Temperature dependence of the Taylor series coefficients and intermodulation distortion characteristics of GaN HEMT

Mohammad Abdul Alim, Mayahsa M. Ali, Ali A. Rezazadeh, Christophe Gaquière

This paper focused on nonlinear distortion modeling and characterization of AlGaN/GaN HEMT on SiC substrate using a two-tone intermodulation measurement. The variation of Taylor series coefficients with temperature: linear terms (G$_m$ and G$_d$$_s$), nonlinear terms (G$_m$$_2$ , G$_m$$_3$ , G$_d$$...

Toward the growth of self-catalyzed ZnO nanowires perpendicular to the surface of silicon and glass substrates, by pulsed laser deposition

Basma El Zein, Yingbang Yao, Ahmad S. Barham, El Hadj Dogheche, Ghassan E. Jabbour

Vertically-oriented zinc oxide (ZnO) nanowires were synthesized on glass and silicon substrates by Pulsed Laser Deposition and without the use of a catalyst. An intermediate c-axis oriented nanotextured ZnO seed layer in the form of nanowall network with honey comb structure allows the growth of...

Scanning Acoustic Microscopy versus Colored Picosecond Acoustics to detect interface defects in hybrid wafer bonding

Solene Bossut, Arnaud Devos, S Lhostis, E Deloffre, C Euvrard, F Dettoni, C Chaton

Nowadays, microelectronics is making progress in miniaturization and diversification of chips by 3D integration: dies are stacked together to gain space and performances. The stacking used here is called hybrid bonding [1], as stacked surfaces are heterogeneous: part Cu and part oxide. After the...

Proof-of-concept millimeter-wave free-space nondestructive testing implemented on collaborative mobile robots

Bilal Daass, Denis Pomorski, Adem Rouibah, Kamel Haddadi

A proof-of-concept nondestructive testing and Evaluation (NDT&E) technique using millimeter-wave electromagnetic sensing is proposed. The method is based on a free-space millimeter-wave characterization instrumentation interfaced with collaborative mobile robots. In particular, 60 GHz emitter...

Photocurrent deviation from linearity in an organic photodetector due to limited hole transport layer conductivity

J. Euvrard, A. Revaux, A. Kahn, Dominique Vuillaume

It has been demonstrated that p-doped polymer layers are a convenient replacement as hole transport layer (HTL) for the widely used Poly(3,4-ethylenedioxythiophene)-poly(styrenesulfonate) (PEDOT:PSS), yielding comparable photodetection performances at low light intensities. In this work, we aim to...

Mechanisms of a rectifying TiN gate contact for AlGaN/GaN HEMTs on silicon substrate

Hassane Ouazzani Chahdi, Brahim Benbakhti, Maghnia Mattalah, Jean Claude Gerbedoen, Abdelatif Jaouad, Nour Eddine Bourzgui, Ali Soltani

Rectifying Titanium Nitride (TiN) gate contact technology is developed for AlGaN/GaN based micro and nanometer HEMTs. A high compressive strain occurring in thinner TiN films (ranging from 5 nm to 60 nm), deposited by sputtering, leads to a reduction in tensile strain at the surface of AlGaN...

Effects of the electrical limit conditions on the electromechanical behavior of piezoelectric transducer arrays

Abdelmajid Bybi, Adil Ammar, Mohammed Garoum, Sébastien Grondel, Ahmed Mzerd, Anne-Christine Hladky

Crosstalk is an undesirable phenomenon having a negative impact on the electroacoustic performance of ultrasonic transducer arrays, utilized in medical imaging and NDT applications. Indeed, when one element of a transducer array is excited, it generates parasitic voltages and/or displacement fields...
