Optimized Buffer Stack with Carbon-Doping for Performance Improvement of GaN HEMTs

Ajay Shanbhag, F Medjdoub, Anjan Chakravorty, Nandita Dasgupta, Amitava Dasgupta

This paper focuses on determining an optimized value of carbon-doping level in the buffer and corresponding channel thickness to improve the performance of GaN HEMTs in terms of subthreshold slope (SS), breakdown voltage (VBD) and transit frequency (ft). With the increase in carbon-doping, we…

HCiT: Deepfake Video Detection Using a Hybrid Model of CNN features and Vision Transformer

Bachir Kaddar, Sid Ahmed Fezza, Wassim Hamidouche, Zahid Akhtar, Abdenour Hadid

The number of new falsified video contents is dramatically increasing, making the need to develop effective deepfake detection methods more urgent than ever. Even though many existing deepfake detection approaches show promising results, the majority of them still suffer from a number of critical…

Growth of earth abundant material based thin films by sputtering technique for photovoltaics, Elaboration de nouveaux matériaux en films minces par pulvérisation cathodique pour cellules solaires

Ngoc Kim Thanh Bui

By literature reports, ZnSnN2 has been pointed out as a potential high bandgap semiconductor material. We particularly investigated on it as an earth abundant and low environmental footprint material for photovoltaic application, and more specifically as a thin film inorganic top absorber for…, Les résultats théoriques publiés sur le matériau ZnSnN2 le font apparaitre comme un matériau semiconducteur à grand gap. Dans ce travail, ses qualités de matériau abondant et à faible empreinte écologique nous ont particulièrement intéressés, en particulier, pour son utilisation en tant que…

Terahertz NH3 Laser with Optical Pumping by “Long” (~100 μs) Pulses of CO2 Laser for Plasma Diagnostics

D. Zazymkina, A. Ionin, I. Kinyaevskiy, Yu. Klimachev, A. Yu. Kozlov, D. Kormashova, A. Kotkov, Jean-Francois Lampin, Yu. Mityagin, S. Savinov, A. Sagitova, D. Sinitsyn, M. Ionin

A terahertz NH3 laser optically pumped by “long” (~100 μs) pulses of an electron-beam-sustained-discharge CO2 laser is demonstrated for the first time. The NH3 laser pulses and the “long” pulses of the CO2 laser are simultaneously measured with nanosecond resolution. The duration and the delay of…

Evaluation of Level-Crossing ADCs for Event-Driven ECG Classification

Maryam Saeed, Qingyuan Wang, Olev Martens, Benoit Larras, Antoine Frappé, Barry Cardiff, John Deepu

In this paper, a new methodology for choosing design parameters of level-crossing analog-to-digital converters (LC-ADCs) is presented that improves sampling accuracy and reduces the data stream rate. Using the MIT-BIH Arrhythmia dataset, several LC-ADC models are designed, simulated and then…

Channel state information-based cryptographic key generation for intelligent transportation systems

Soheyb Ribouh, Kelvin Phan, Arnav Vaibhav Malawade, Yassin El Hillali, Atika Rivenq, Mohammad Abdullah Al Faruque

Due to the sensitivity of the information exchanged in Vehicle to Vehicle (V2V) and Vehicle to Infrastructure (V2I) communication, generating secret keys is critical to secure these communications. As nature is open access, distributed keys are more vulnerable to attacks in the vehicular…

Design and fabrication of a perylene dimiide functionalized g-C3N4@UiO-66 supramolecular photocatalyst: Insight into enhancing the photocatalytic performance

Anasheh Mardiroosi, Ali Reza Mahjoub, Hanieh Fakhri, Rabah Boukherroub

Photocatalytic degradation of organic pollutants (dyes, drugs, pesticides...) is of high interest. In this study, a unique supramolecular architecture of perylene diimide functionalized graphitic carbon nitride (PCN) was prepared and used as a support for UiO-66 nanoparticles. The organic-inorganic…

High Rectification Ratio in Polymer Diode Rectifier through Interface Engineering with Self-Assembled Monolayer

Khaoula Ferchichi, Sébastien Pecqueur, David Guérin, Ramzi Bourguiga, Kamal Lmimouni

In this work, we demonstrate P3HT (poly 3-hexylthiophene) organic rectifier diode both in rigid and flexible substrate with a rectification ratio up to 106. This performance has been achieved through tuning the work function of gold with a self-assembled monolayer of 2,3,4,5,6-…
