Atomic layer deposition was employed to coat the aerogel template conformally with various thicknesses of TiO 2 with subnanometer precision. The TiO 2-coated aerogel membranes were incorporated as photoanodes in dye-sensitized solar cells. The charge diffusion length was found to increase with increasing thickness of TiO 2 leading to increasing current and efficiency. Initial devices exhibited power conversion efficiencies of up to 4.3% under 100 W m-2 light intensity. The novel fabrication technique provides a facile, oxide materials general method to prepare high surface area pseudo-one-dimensional DSSC photoanodes with promising performance.

High Sensitivity Refractometer Based on TiO2-Coated Adiabatic Tapered Optical Fiber via ALD Technology

Atomic layer deposition (ALD) technology is introduced to fabricate a high sensitivity refractometer based on an adiabatic tapered optical fiber. Different thicknesses of titanium dioxide (TiO₂) nanofilm were coated around the tapered fiber precisely and uniformly under different deposition cycles. Attributed to the higher refractive index of the TiO₂ nanofilm compared to that of silica, an asy...

The Effect of Annealing Treatment and Atom Layer Deposition to Au/Pt Nanoparticles-Decorated TiO₂ Nanorods as Photocatalysts.

The wide band gap of TiO₂ hinders the utilization of visible light in high-performance photocatalysis. Herein, vertically aligned Ti nanopillar arrays (NPAs) were grown by the glancing angle deposition method (GLAD) and then thermally oxidized into TiO₂ NPAs. The metallic nanoparticles (NPs) were fabricated by successive ion layer adsorption and reaction (SILAR) method. And we covered ultrathin...

The Effect of Film Thickness on the Gas Sensing Properties of Ultra-Thin TiO2 Films Deposited by Atomic Layer Deposition

Analyte sensitivity for gas sensors based on semiconducting metal oxides should be highly dependent on the film thickness, particularly when that thickness is on the order of the Debye length. This thickness dependence has previously been demonstrated for SnO₂ and inferred for TiO₂. In this paper, TiO₂ thin films have been prepared by Atomic Layer Deposition (ALD) using titanium isopropoxide an...

Dioxide ( TiO 2 ) using Poly ( methyl methacrylate ) ( PMMA )

The Minnesota Nano Center’s Keller Hall facility includes an atomic layer deposition (ALD) machine that is capable of depositing uniform alumina (Al2O3), hafnium oxide (HfO2), silicon dioxide (SiO2), zinc oxide (ZnO), and titanium dioxide (TiO2). ALD works by building alternate layers on a film using two different precursor gases – one usually supplying the metallic atoms and water vapor (H2O) ...
