A. Buryakov, A. Gorbatova, P. Avdeev, E. Lebedeva, K. Brekhov, A. Ovchinnikov, N. Gusev, E. Karashtin, M. Sapozhnikov, E. Mishina, N. Tiercelin, V.L. Preobrazhensky

We report on the design of a spintronic emitter based on the Pt(3 nm)/Co(3 nm) structure, which enables the control over terahertz radiation polarization. Utilizing the field-induced magnetization rotation that takes place at low magnetic fields of up to 250 Oe at room temperature, we have achieved...

Highly-sensitive SERS detection of tetracycline: Sub-enhancement brought by light scattering of nano-diamond

Jingxuan Pei, Zhenfei Tian, Xiang Yu, Shuting Zhang, Shiqing Ma, Yibo Sun, Rabah Boukherroub

Antibiotic residues in wastewater cause a serious threat to aquatic environment and human safety. Therefore, the development of robust strategies for detecting antibiotic residues becomes critical. In this work, a surface-enhanced Raman scattering (SERS) substrate, consisting of gold nanoparticles/...

Unsupervised and efficient learning in sparsely activated convolutional spiking neural networks enabled by voltage-dependent synaptic plasticity

Gaspard Goupy, Alexandre Juneau-Fecteau, Nikhil Garg, Ismael Balafrej, F. Alibart, Luc Frechette, Dominique Drouin, Yann Beilliard

Spiking neural networks (SNNs) are gaining attention due to their energy-efficient computing ability, making them relevant for implementation on low-power neuromorphic hardware. Their biological plausibility has permitted them to benefit from unsupervised learning with bio-inspired plasticity rules...

Spin Seebeck effect and thermal properties of zigzag graphene nanoribbons with edge magnetism

Jing Li, Yann-Michel Niquet, Christophe Delerue

Zigzag graphene nanoribbons (GNRs), demonstrating edge magnetism, are fascinating materials for electronic and spintronic applications. In this paper, we investigate with explicit consideration of electron-phonon scattering the Seebeck effect and thermal conductivity at various carrier densities in...

Signal Denoising and Detection for Uplink in LoRa Networks based on Bayesian-optimized Deep Neural Networks

Angesom Ataklity Tesfay, Sofiane Kharbech, Eric Pierre Simon, Laurent Clavier

Long-range and low-power communications are suitable technologies for the Internet of things networks. The long-range implies a very low signal-to-noise ratio at the receiver. In addition, low power consumption requires reduced signaling, hence the use of less complex protocols, such as ALOHA, so...

Space-time Modulation in a Piezoelectric Phononic Crystal: Experimental Study in Sub-sonic and Sonic Regimes

Sarah Tessier Brothelande, Charles Croenne, Florian Allein, Jerome Vasseur, Bertrand Dubus

We experimentally study acoustic wave propagation in a spatio-temporally modulated system for different modulation speeds, up to the sonic regime when the modulation speed is similar to the wave propagation speed. The system under study is a piezoelectric phononic crystal whose electrical boundary...
