Abstract
Dynamic shadowing growth (DSG)isa simple nanofabrication technique that combines oblique angledeposition (OAD) with substrate manipulations and source controls in a physical vapor deposition system. The geometry shadowing effect is the dominant growth mechanism resulting in the formation of various nanostructure arrays by programming the substrate rotation in polar and/or azimuthal direction. With recent advance in a multilayer deposition procedure, one can design complex and multifunctional heterogeneous nanostructures. In addition, with a co-deposition system of two or more sources, novel nanocomposites or doped nanostructure arrayscan be produced, which results in nanostructures with different morphology and functionality. In this talk, we will highlight some of the recent progress in nanofabrication by DSG and its applications in nanomotor, biodetection, novel photocatalysts and battery anodes.
