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.
