摘要： Novel cyclic amides containing tin or lead are disclosed. These cyclic amides can be used for atomic layer deposition or chemical vapor deposition of tin or lead as well as their oxides, sulfides, selenides, nitrides, phosphides, carbides, silicides or borides or other compounds. Tin(IV) oxide, SnO2, films were deposited by reaction of a cyclic tin amide vapor and H2O2 or NO2 as oxygen sources. The films have high purity, smoothness, transparency, electrical conductivity, density, and uniform thickness even inside very narrow holes or trenches. Deposition temperatures are low enough for thermally sensitive substrates such as plastics. Suitable applications of these films include displays, light-emitting diodes, solar cells and gas sensors. Doping SnO2 with aluminum was used to reduce its conductivity, making material suitable as the active semiconductor layer in electron multipliers or transparent transistors. Deposition using the same tin precursor and H2S deposited tin monosulfide, SnS, a material suitable for solar cells.

摘要： A surface-enhanced Raman spectroscopy (SERS) substrate formed from a plurality of monolayers of polyhedral silver nanocrystals, wherein at least one of the monolayers has polyvinypyrrolidone (PVP) on its surface, and thereby configured for sensing arsenic is described. Highly active SERS substrates are formed by assembling high density monolayers of differently shaped silver nanocrystals onto a solid support. SERS detection is performed directly on this substrate by placing a droplet of the analyte solution onto the nanocrystal monolayer. Adsorbed polymer, polyvinypyrrolidone (PVP), on the surface of the nanoparticles facilitates the binding of both arsenate and arsenite near the silver surface, allowing for highly accurate and sensitive detection capabilities.
