The Effect of C60 and Pentacene Adsorbates on the Electrical Properties of CVD Graphene on SiO2

Jacopo Oswald, Davide Beretta, Michael Stiefel, Roman Furrer, Dominique Vuillaume, Michel Calame

Graphene is an excellent 2D material for vertical organic transistors electrodes due to its weak electrostatic screening and field-tunable work function, in addition to its high conductivity, flexibility and optical transparency. Nevertheless, the interaction between graphene and other carbon-based…

Effects of Reaction Parameters on the Geometry and Crystallinity of Hydrothermally Synthesized ZnO Nanorods for Bio-Fouling Applications

Abderrahmane Hamdi, Chin Sing Lim, Mohamed Aymen Ben Achour, Ali Ahmed Alshehri, Mervat Alamri, D. Deresmes, Serena Lay-Ming Teo, Denis Remiens, El Hadj Dogheche

In this present work, we have successfully synthesized vertical aligned ZnO nanorod arrays (ZnO NRs) on conductive stainless-steel substrate. These ZnO NRs were obtained by using a low temperature, low cost, and eco-friendly hydrothermal approach. The effect of the sol-gel deposited ZnO seed layer…

High-field 1/f noise in hBN-encapsulated graphene transistors

A. Schmitt, D. Mele, Michael Rosticher, T. Taniguchi, K. Watanabe, C. Maestre, C. Journet, V. Garnier, Gwendal Fève, J. Berroir, Christophe Voisin, B. Plaçais, Emmanuel Baudin

Low-frequency 1/f noise in electronics is a conductance fluctuation, that has been expressed in terms of a mobility ”α-noise” by Hooge and Kleinpenning. Understanding this noise in graphene is a key towards high-performance electronics. Early investigations in diffusive graphene have pointed out a…

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…
