Low Source/Drain Contact Resistance for AlGaN/GaN HEMTs with High Al Concentration and Si-HP [111] Substrate

Steven Duffy, Brahim Benbakhti, Maghnia Mattalah, Wei Zhang, Meriem Bouchilaoun, Mohammed Boucherta, Karol Kalna, Nour Eddine Bourzgui, Maher, Hassan, Ali Soltani

An optimized fabrication process of ohmic contacts is proposed to reduce the source/drain access resistance (RC) and enhance DC/RF performance of AlGaN/GaN HEMTs with a high Al concentration. We show that source/drain RC can be considerably lowered by (i) optimally etching into the barrier layer…

A comprehensive study of magnetic exchanges in the layered oxychalcogenides Sr3Fe2O5Cu2Q2 (Q = S, Se)

Minfeng Lü, Olivier Mentre, Elijah E. Gordon, Myung-Hwan Whangbo, Alain Wattiaux, Mathieu Duttine, Nicolas Tiercelin, Houria Kabbour

The layered oxysulfide Sr3Fe2O5Cu2S2 was prepared, and its crystal structure and magnetic properties were characterized by synchrotron X-ray diffraction (XRD), powder neutron diffraction (PND), Mössbauer spectroscopy measurements and by density functional theory (DFT) calculations. In addition, the…

A 65-nm CMOS 7fJ per synaptic event clique-based neural network in scalable architecture

Benoit Larras, Paul Chollet, Cyril Lahuec, Fabrice Seguin, Matthieu Arzel

Clique-based neural networks are less complex than commonly used neural network models. They have a limited connectivity and are composed of simple functions. They are thus adapted to implement neuro-inspired computation units operating under severe energy constraints. This paper shows an ST 65-nm…

Approach-to-equilibrium molecular dynamics

Évelyne Martin, Pier Luca Palla, H. Zaoui, Fabrizio Cleri

Besides steady-state methods presented in Chapters 8 and 9, molecular dynamics simulations can also be used to simulate temperature transients, by means of approach-to-equilibrium molecular dynamics (AEMD) calculations. The interest for such methods is materialso the short MD simulation time…

Photothermally triggered on-demand insulin release from reduced graphene oxide modified hydrogels

Florina Teodorescu, Yavuz Oz, Gurvan Queniat, Amar Abderrahmani, Catherine Foulon, Marie Lecoeur, Rana Sanal, Amitav Sanyal, Rabah Boukherroub, Sabine Szunerits

On-demand delivery of therapeutics plays an essential role in simplifying and improving patient care. The high loading capacity of reduced graphene oxide (rGO) for drugs has made this matrix of particular interest for its hybridization with therapeutics. In this work, we describe the formulation of…

An ultra broadband 0.5-18 GHz BPSK modulator

Paul Sangare, Christophe Loyez, Kevin Carpentier, Markus Mayer, Dirk Hartung, Francois Parickmiler, Nathalie Rolland

This paper presents an innovative topology of an ultra-broadband BPSK modulator. This novel architecture consists of a specific distributed amplifier and absorptive switches, providing amplitude flatness and low phase imbalance over the 0.5 - 18 GHz frequency bandwidth. Experimental results…
