THE concept of a surface film obstructing the egress of dislocations from a crystal and thereby causing them to pile-up beneath the film has proved useful in explaining the results of several ...

With a bandgap of just over 6 eV, AlN promises to provide ground-breaking power-electronic devices. But its success is ...

Metals and alloys are materials that are typically hard, malleable, and have good electrical and thermal conductivity. Alloys are made by melting two or more elements together, at least one of them a ...
