Radiation damage bigger problem in microelectronics than previously thought

The amount of damage that radiation causes in electronic materials may be at least ten times greater than previously thought. That is the surprising result of a new characterization method that uses a combination of lasers and acoustic waves to provide scientists with a capability tantamount to X-ray vision: It allows them to peer through solid materials to pinpoint the size and location of detects buried deep inside with unprecedented precision.

Electrons get off the track - Scientists find new principle for spin transistor

Researchers have made a significant step in utilizing the electrons' spin for transistor action. If spin-based electronics prevails the new switching concept might turn out to be useful as it allows for switching the spin-polarization of an electric current on and off, tuning it continuously or reading it off electrically by simple resistance measurements.

Probing the role of disorder in quantum coherence

A new experiment conducted at the Joint Quantum Institute examines the relationship between quantum coherence, an important aspect of certain materials kept at low temperature, and the imperfections in those materials. These findings should be useful in forging a better understanding of disorder, and in turn in developing better quantum-based devices, such as superconducting magnets.

'Loops of light' promising for optical detection of individual molecules

KU Leuven researcher Ventsislav Valev and an international team of colleagues have developed a new method for manipulating light at the nanoscale in order to optically detect single molecules. By shining circularly polarised light on a gold, square-ring shaped nanostructure, the researchers were able to 'activate' the entire surface of the nanostructure, thereby significantly increasing the opportunity for interaction with molecules.
