报告摘要:

A viable technique that can produce nanostructures massively and cost-efficiently is essential to realize the promise of nanotechnology. In this talk, a novel nanofabrication technique, as we called it as “dynamic oblique angle deposition”, will be introduced. It has been developed by several groups including us in the past few years to produce three-dimensional (3D) nanostructures of a large variety of materials. This technique combines oblique angle deposition with substrate motions in a physical vapor deposition system to produce 3D nanostructure arrays.

In this talk, I will focus on our current understanding of the growth mechanisms in dynamic oblique angle deposition and present the abnormal growth behaviors in certain metals, calcium fluoride, and titanium nitride. In addition, I will demonstrate unique properties and possible applications of metal and fluoride nanostructures fabricated in our lab.
