The development of a scalable platform by which to in situ synthesize metal chalcogenide nanostructures will address one of the biggest challenges in nanotechnology: the integration of nanostructures in practical devices. Semiconductor Nanowire Deposition On Micropatterned substrates (SENDOM) will be developed for in situ formation of semiconductor nanowires, nanopores, nanochannels, nanosheets and patterned nanofilms, and for fabrication of complex nanostructures including nanowire-based transistors. In SENDOM a multifunctional micropatterned surface is used to direct the growth of nanowires by chemical bath deposition (CBD). SENDOM can create nanowires that are centimeters long and that follow complex paths. These methods will be studied mechanistically, optimized, and extended to a wide range of nanostructures, including nanopores and nanochannels, materials and substrates. By leveraging the expertise gained, CBD-based preparation of in situ site specifically deposited and free-standing transition metal dichalcogenide (TMD) nanosheets, in particular nanosheets of MoS2, MoSe2, HfS2 and TiS2, will also be demonstrated.
