Doping crystals of nanocrystals

Crucial to silicon semidconductor applications is the ability to 'dope' the semiconductor; which is to say, by controllably adding impurity atoms to a semiconductor, one can continuously vary its electronic and optical properties. Scientists now have demonstrated for the first time, a unique nanoscale analogue.

Frustrated magnets point towards new memory

Theoretical physicists have discovered that so-called 'frustrated magnets' can produce skyrmions, tiny magnetic vortices that may be used in memory storage. This discovery opens up a new class of materials for scientists working on 'skyrmionics', which aims to build memory and logic devices based on skyrmions.
