Probing Spintronic Features in Conduction through Silicene and Graphene Barriers

The Dirac electrons in silicene experience stronger spin-orbit interaction (SOI) than in graphene due to silicene's band buckled two-dimensional (2D) structure. In this work we theoretically probe the main effects of the SOI in silicene, provided this interaction can be controlled by an external electrical field. Attention is paid to how silicene's SOI effects can turn into...

A Combined Energy Management Algorithm for Wind Turbine/Battery Hybrid System

From an energy management standpoint, natural phenomena such as solar irradiation and wind speed are uncontrolled variables, so the correlation between the energy generated by renewable energy sources and energy demand cannot always be predicted. For this reason, energy storage systems are used to provide more efficient renewable energy systems. In these systems, energy...

A Mechanistic Thermal Fatigue Model for SnAgCu Solder Joints

The present work offers both a complete, quantitative model and a conservative acceleration factor expression for the life span of SnAgCu solder joints in thermal cycling. A broad range of thermal cycling experiments, conducted over many years, has revealed a series of systematic trends that are not compatible with common damage functions or constitutive relations. Complementary...

In the original article some funding information in the Acknowledgements section was inadvertently omitted. Following is the corrected text.

Interface-Dependent Effective Mobility in Graphene Field-Effect Transistors

By pretreating the substrate of a graphene field-effect transistor (G-FET), a stable unipolar transfer characteristic, instead of the typical V-shape ambipolar behavior, has been demonstrated. This behavior is achieved through functionalization of the SiO2/Si substrate that changes the SiO2 surface from hydrophilic to hydrophobic, in combination with postdeposition of an Al2O3...

Crystallographic Orientation Identification in Multicrystalline Silicon Wafers Using NIR Transmission Intensity

Near-infrared (NIR) polariscopy is a technique used for the non-destructive evaluation of the in-plane stresses in photovoltaic silicon wafers. Accurate evaluation of these stresses requires correct identification of the stress-optic coefficient, a material property which relates photoelastic parameters to physical stresses. The material stress-optic coefficient of silicon varies...
