Abstract
The present invention is directed to a novel synthetic method for producing nanoscale heterostructures, and particularly nanoscale heterostructure particles, rods and sheets, that comprise a metal core and a monocrystalline semiconductor shell with substantial lattice mismatches between them. More specifically, the invention concerns the use of controlled soft acid-base coordination reactions between molecular complexes and colloidal nanostructures to drive the nanoscale monocrystalline growth of the semiconductor shell with a lattice structure incommensurate with that of the core. The invention also relates to more complex hybrid core-shell structures that exhibit azimuthal and radial nano-tailoring of structures. The invention is additionally directed to the use of such compositions in semiconductor devices.
