Influence of electrical properties on thermal boundary conductance at metal/semiconductor interface

Quentin Pompidou, Juan Carlos Acosta Abanto, M. Brouillard, Nicolas Bercu, L. Giraudet, Rami Sheikh, C. Adessi, S. Mérabia, S. Gomès, Pierre-Olivier Chapuis, J.-F. Robillard, Mihai Chirtoc, N. Horny

Recent experimental investigations have demonstrated that doping a semiconductor is a route to increase the thermal boundary conductance at metal/semiconductor interfaces. In this work, the influence of the electrical properties on heat transfer across metal/doped semiconductor junctions is…

A HCN terahertz molecular laser pumped by a QCL

Alexandra Khabbaz, Roland Teissier, Gael Mouret, Jean-François Lampin

In this communication we show for the first time that the optical pumping of the HCN molecule allows THz generation. The pumping source is a quantum cascade laser with a wavelength around 14 μm. THz lasing is achieved on nine different transitions from 0.27 to 0.97 THz.

Unsupervised local learning based on voltage-dependent synaptic plasticity for resistive and ferroelectric synapses

Nikhil Garg, Ismael Balafrej, Joao Henrique Quintino Palhares, Laura Bégon-Lours, Davide Florini, Donato Francesco Falcone, Tommaso Stecconi, Valeria Bragaglia, Bert Jan Offrein, Jean-Michel Portal, Damien Querlioz, Yann Beilliard, Dominique Drouin, Fabien Alibart

The deployment of AI on edge computing devices faces significant challenges related to energy consumption and functionality. These devices could greatly benefit from brain-inspired learning mechanisms, allowing for real-time adaptation while using low-power. In-memory computing with nanoscale…

Competing effects of charge-carrier and impurity scattering limiting phonon heat conduction in heavily-doped silicon

Raja Sen, Juan Carlos Acosta Abanto, Mélanie Brouillard, Séverine Gomès, Jean-François Robillard, Alessandro Ciavatta, Lorenzo Paulatto, Nathalie Vast, Jérôme Saint-Martin, Jelena Sjakste, Pierre-Olivier Chapuis

With respect to undoped semiconductors, thermal transport by phonons is limited by two additional mechanisms when doping increases: charge-carrier and impurity scattering. Previous works provided contradicting conclusions on the dominant doping-induced scattering mechanism in silicon. In this work…
