PROCESSING OF SINGLE NANOCRYSTALS

Nanocrystal processing (NXP) is introduced as a rational approach, bas ed on solid-state thermodynamics and surface chemistry, toward the pre paration of perfect and stable nanometer-scale single crystals. Select ed facts from the descent of fullerenes are first recalled. The termin ology and motivation of nanocrystals and NXP are defined and outlined. The elements of NXP are then delineated in generic terms, with refere nce to known surface chemistry. Illustrations of etching and passivati on processes from the chemistry of ionic nanocrystals and aerosols are given. Prospects for the implementation of NXP are then discussed.
