Investigation into integrated PEC/PVC for water splitting and light harvesting has focused on doping, QD sensitization and nanomaterials morphology. We have demonstrated, for the first time, PVC based on combined use of nitrogen doping and CdSe QD sensitization of nanocrystalline TiO2 thin films with promising results for solar energy conversion. Such TiO2:N/CdSe PVC produced an incident-photon...

In this work, the preparation of regular nanosized columnar structures titanium dioxide by means glancing angle deposition with magnetron sputtering (MS-GLAD) followed thermal annealing is reported. MS-GLAD gives rise to metallic width and length that after treatment are fully oxidized form TiO2 nanocolumns maintain morphological features original ones. Further functionalization gold multiple i...

There is intense and growing interest in one-dimensional (1-D) nanostructures from the perspective of their synthesis and unique properties, especially with respect to their excellent optical response and an ability to form heterostructures. This review discusses alternative approaches to preparation and organization of such structures, and their potential properties. In particular, molecular-s...

Glancing angle deposition (GLAD) is a specific type of physical vapor that has the unique ability to generate three-dimensional nanofeatures in process-efficient and low-cost manner. Our research group previously demonstrated how line seeds can be strategically implemented create variety novel well-organized nanostructures. In this paper we explore use spherical self-assemble into hexagonally c...

Three-dimensional nanostructures can be fabricated by the glancing angle deposition technique. By rotating the substrate in both polar and azimuthal directions, one can fabricate desired nanostructures, such as nanorod arrays with different shapes, nanospring arrays, and even multilayer nanostructures. This method offers a fully three-dimensional control of the nanostructure with additional cap...

UNLABELLED Large-area periodically aligned silicon nanopillar (PASiNP) arrays were fabricated by magnetic sputtering with glancing angle deposition (GLAD) on substrates coated by a monolayer of close-packed polystyrene (PS) nanospheres. The structure of PASiNP arrays could be manipulated by changing the diameter of PS nanospheres. Enhanced light absorptance within a wavelength range from 300 to...
