Electron billiards in nanoscale circuits

In solar cells, solar radiation boosts electrons to higher energy states, thereby releasing them from their atomic bonds as electricity begins to flow. Scientists led by Professor Alexander Holleitner, physicist at the Technische Universitaet Muenchen, have developed a novel method to analyze the way photogenerated electrons move in the smallest photodetectors.

The electronics for smart brain implants

Imagine that, one day, we would be able to implant electronics in the brain. Electronics that restore damaged regions of the brain. Or impaired functions, such as speech, hearing, vision, movement control, or even memory.

Au-free Si-processing compatible GaN power devices on 6 inch Si wafers

Imec and its partners have successfully fabricated Au-free, Si-processing compatible GaN power devices on a 6 inch Si wafer. This result is a milestone in imec's industrial affiliation program (IIAP) on GaN power and light-emitting (LED) devices that targets cost reduction as one of the main objectives.

Smaller is better in the viscous zone

Being the right size and existing in the limbo between a solid and a liquid state appear to be the secrets to improving the efficiency of chemical catalysts that can create better nanoparticles or more efficient energy sources.

Light on silicon better than copper?

As good as the metal has been in zipping information from one circuit to another on silicon inside computers and other electronic devices, optical signals can carry much more, according to Duke University electrical engineers. So the engineers have designed and demonstrated microscopically small lasers integrated with thin film-light guides on silicon that could replace the copper in a host of electronic products.

A forest of nanorods

Just as landscape photographs shot in low-angle light dramatically accentuate subtle swales and mounds, depositing metal vapors at glancing angles turns a rough surface into amazing nanostructures with a vast range of potential properties.
