Description
Summary:In this letter, we reported nanocrystal floating gate memory with Co–SiO2 core-shell nanocrystal charge storage nodes. By using a water-in-oil microemulsion scheme, Co–SiO2 core-shell nanocrystals were synthesized and closely packed to achieve high density matrix in the floating gate without aggregation. The insulator shell also can help to increase the thermal stability of the nanocrystal metal core during the fabrication process to improve memory performance. At the request of the authors, this article is being retracted effective 1 July 2010.
