Energy Efficient Hardware and Improved Cluster-Tree Topology for Lifetime Prolongation in ZigBee Sensor Networks

Mourad Ouadou, Ouadoudi Zytoune, Yassin El Hillali, Atika Rivenq, Driss Aboutajdine

In wireless sensor networks, building energy-efficient systems is one of the major challenges. In such networks, nodes are usually supplied by low power and small batteries. Many factors are involved in the energy consumption, and this issue may be considered as a cross-layer problem, from the…

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…
