A Theoretical Analysis of the Frequency Response in p-i-n Photodiodes that Use InGaAs/InP Materials

Nesrine Bakalem, Abdelkader Aissat, Samuel Dupont, Faouzi Saidi, Mohamed Houcine Dhaou, Jean Pierre Vilcot

This investigation is centered on the analysis of frequency response characteristics of a p-i-n photodiode using InxGa$_{1-x}$As/InP. The InGaAs/InP can be developed under three conditions: compression, tensile strain, and lattice matching. Initially, we performed calculations on strain, bandgap...

Pinces acoustiques hautes fréquences pour la manipulation d'objets micrométriques

Jean-Louis Thomas, Michael Baudoin, Roudy Al Sahely

Les pinces acoustiques sont l’équivalent des pinces optiques, elles utilisent un faisceau focalisé pour piéger en trois dimension un objet à l’aide de la pression de radiation. Ces dernières ont permis de faire des manipulation d’objets micro-métrique avec une précision nano-métrique. Néanmoins une...

Rethinking Attention Gated with Hybrid Dual Pyramid Transformer-CNN for Generalized Segmentation in Medical Imaging

Fares Bougourzi, Fadi Dornaika, Abdelmalik Taleb-Ahmed, Vinh Truong Hoang

Inspired by the success of Transformers in Computer vision, Transformers have been widely investigated for medical imaging segmentation. However, most of Transformer architecture are using the recent transformer architectures as encoder or as parallel encoder with the CNN encoder. In this paper, we...

Elastic wave propagation in diatom frustules

Chiara Gazzola, Xin Zhou, David Troadec, Marco Miniaci

Diatoms are microscopic algae encapsulated inside a silica inorganic exoskeleton called frustule featuring a complex quasi-regular and hierarchical distribution of micro- and nano-scaled pores. The mechanical and optical behaviors of these biological systems have already been investigated in...

Surface oxidation and oxygen incorporation in ScAlN films grown by molecular beam epitaxy

Valentina Gallardo-Mödinger, Frédéric Georgi, Xavier Wallart, Ileana Florea, Philippe Vennéguès, Yvon Cordier, Maxime Hugues

Recently, there has been much interest in the ScAlN alloy, thanks to its various potential applications in high-frequency high-power, acoustoelectric, and ferroelectric devices. Nonetheless, these applications could be impaired by the presence of oxygen in the alloy and the formation of a surface...
