Fuctionalization of single silicon nanocrystals by connecting with multiwalled carbon nanotubes.

Two approaches to connect single silicon nanocrystals (Si-nc) with multiwalled carbon nanotubes (MWCNTs) are studied. The first consists of direct growth of the MWCNTs in tapered element oscillating microbalance by chemical vapour deposition process on coated Si-nc with iron based catalyst. The second procedure, at room temperature connects and introduces dispersed Si-nc (2– 5 nm) in colloidal suspension of spin on glass by capillary forces. © 2005 American Institute of Physics [ABSTRACT FROM AUTHOR]
