Nonvolatile memory with Co - SiO 2 core-shell nanocrystals as charge storage nodes in floating gate

In this letter, we reported nanocrystal floating gate memory with Co - SiO 2 core-shell nanocrystal charge storage nodes. By using a water-in-oil microemulsion scheme, Co - SiO 2 core-shell nanocrystals were synthesized and closely packed to achieve high density matrix in the floating gate without a...

Description
Summary:In this letter, we reported nanocrystal floating gate memory with Co - SiO 2 core-shell nanocrystal charge storage nodes. By using a water-in-oil microemulsion scheme, Co - SiO 2 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.
