[Invited] Process challenges and perspectives of vertical GaN power transistors on foreign substrates

Christian Huber, S. Regensburger, E. Bahat-Treidel, F Medjdoub, Jens Baringhaus

Despite considerable progress in their process technology during the last years, vertical GaN power transistors are currently not finding market entry due to the small size and high cost of native GaN substrates. This issue can in principle be circumvented by using heteroepitaxial GaN on more…

Comparison of AlGaN/GaN High Electron Mobility Transistors grown by MOVPE on 3C-SiC/Si(111), Si(111) and 6H-SiC for RF applications

Marie Lesecq, Éric Frayssinet, Marc Portail, Micka Bah, Nicolas Defrance, Thi Huong Ngo, Mahmoud Abou Daher, Ali Abboud, Yassine Fouzi, Marcin Zielinski, Daniel Alquier, Jean-Claude de Jaeger, Yvon Cordier

In spite of their outstanding performances for microwave power applications, transistors based on GaN-on-SiC [1] suffer from the lower availability and higher cost of the substrate compared to Silicon ones permitting also to get GaN devices interesting high frequency performances [2]. However,…

Comparison of GaN and InGaAs high electron mobility transistors as zero-bias microwave detectors

G. Paz-Martínez, I. Íñiguez-De-La-Torre, H. Sánchez-Martín, B. García-Vasallo, Nicolas Wichmann, T. González, J. Mateos

We report on the measurements of the two main figures of merit for microwave detection, namely, responsivity and noise equivalent power (NEP), in HEMTs based on two of the most broadly used material systems AlGaN/GaN and AlInAs/InGaAs. A comparison between their performances as RF detectors in a…

Scanning microwave microscopy for detecting mechanical vibrations of silicon nitride membranes

Hao Xu, Didier Theron, X Zhou

Highly stressed silicon nitride mechanical resonators, due to nanogram effective mass and high resonance frequency in megahertz, are attractive for various sensing applications [1]. Unlike optical readout schemes, electrical detections of tiny displacements from silicon nitride resonators are more…

Image Style Transferred to Graphical User Interfaces

Karim Hammoudi, Adnane Cabani, Halim Benhabiles, Mahmoud Melkemi

This paper presents an approach for permitting the restyling of an application by automatic analysis of a considered image. The approach relies on the analysis of color distribution from a query image and a color-to-component mapping in order to perform its style transfer to the GUI. No deep…
