In this work, gate dielectric degradation under dynamic Fowler-Nordheim (FN) stress is studied. A novel interface characterization technique, direct-current current-voltage (DCIV) technique, is used to measure the interface trap generation caused by dynamic FN stress. The dependence of interface trap generation on stress time is always found to follow a power-law, which is similar to the situat...

Nowadays total joint replacements are widely used in the world, so in average 800,000 joint surgeries are done yearly only in Europe and North America. However implant loosening is and remains as the major issue of all implant failures and therefore causes revision surgery procedures. Studies and experiments have identified poor fixation of implants most likely is the main cause of long term im...

Although the adhesion phenomenon is crucial in achieving and maintaining a composite building on dental structure, this phenomenon is not completely understood. On the other hand, adhesion is dependent on the interface quality (the interface between enamel and adhesive). In this study, the authors approached the subject of the influence of adhesive clinical application on the composite-enamel i...

Several structures need their response to blast loads be investigated grant an acceptable survivability level. To this purpose, experimental campaigns are complex, but some numerical methods commonly exploited. The explosion pressure-time history is typically estimated characterizing the detonation of energetically equivalent involving a specific amount TNT. at point, fixed in space, involved b...

The influence of a c(2x2) ordered interface alloy of 3d transition metals at the ferromagnet/nonmagnet interface on interlayer exchange coupling (IXC), the formation of quantum well states (QWS) and the phenomenon of Giant MagnetoRe-sistance is investigated. We obtained a strong dependence of IXC on interface alloy formation. The GMR ratio is also strongly influenced. We found that Fe, Ni and C...

The dynamics of an interface connecting a stationary stripe pattern with a homogeneous state is studied. The conventional approach which describes this interface, Newell–Whitehead–Segel amplitude equation, does not account for the rich dynamics exhibited by these interfaces. By amending this amplitude equation with a nonresonate term, we can describe this interface and its dynamics in a unified...
