Findings from University of California in Nanowires Reported (Uniform Doping of Metal Oxide Nanowires Using Solid State Diffusion)

September 3, 2014



By a News Reporter-Staff News Editor at Biotech Week -- New research on Nanowires is the subject of a report. According to news reporting originating in Berkeley, California, by NewsRx journalists, research stated, "The synthesis of one-dimensional nanostructures with specific properties is often hindered by difficulty in tuning the material composition without sacrificing morphology and material quality. Here, we present a simple solid state diffusion method utilizing atomic layer deposition to controllably alter the composition of metal oxide nanowires."

The news reporters obtained a quote from the research from the University of California, "This compositional control allows for modification of the optical, electronic, and electrochemical properties of the semiconductor nanowires. Using this method and a novel process for manganese oxide atomic layer deposition, we produced manganese-doped rutile TiO2 nanowires and investigated their structural and photoelectrochemical properties. A homogeneous incorporation of the Mn dopant into the rutile lattice was observed, and the local chemical environment of the Mn was determined using X-ray absorption spectroscopy."

According to the news reporters, the research concluded: "The doping process resulted in a tunable enhancement in the electrocatalytic activity for water oxidation, demonstrating that this simple and general method can be used to control the properties of one-dimensional nanostructures for use in a variety of applications including solar-to-fuel generation."
