【書報討論】105/5/5 SLAC National Accelerator Laboratory 張傑博士
日期/時間：2016-5-5(四) 3:30PM～5:00PM
地點：清華大學工程一館107演講廳
演講題目：操控X光？談奈米科技如何解決此難題
演講者： SLAC National Accelerator Laboratory 張傑博士
演講大綱：
Recent advances in nanofabrication technology have enabled new applications that require nanoscale structures to possess novel properties or perform new functions. Among all the applications, diffractive x-ray optics poses the most difficult challenges in its fabrication, as it requires patterning dense, complex, high resolution, and high aspect ratio nanostructures in order to control and manipulate x-ray beams in time and space.
In the first part of my talk, I will review various state-of-the-art nanofabrication techniques that have allowed x-ray diffractive optics to be implemented and improved over time, yet still having their own limitations in various aspects. In the second part of my talk, I will describe how we to tackle those challenges via vertical directionality-controlled metal-assisted chemical etching (V-MaCE), a nanofabrication technology that we developed in SLAC. V-MaCE is capable of fabricating ultra high aspect ratio, high resolution nanoscale structures as diffractive X-ray optics for the use in the scientifically rich hard x-ray regime. Finally, I will describe new research directions enabled by V-MaCE for potential applications in energy storage and generation.
