Organic Deformable Mirror for Adaptive Optics
, 2007 中文摘要 可形變面鏡用於天文觀測上已行之有年，近年來在生物醫學、光衰減器、微型成像系統的應用上有不少的突破。在本篇論文中，我將探討有機光學薄膜製程上所遭遇到的問題及其解決方法。另外我們提出微型有機薄膜架構的設計，此設計改良了一般有機薄膜在製作上的精準度問題，並進一步解決了有機薄膜可形變面鏡晶片的封裝問題。 我們選擇了低殘餘應力的有機材料，使用微機電製程製造出一微米厚度的有機薄膜，並在此薄膜上使用黃光製程定義出我們所需要的開孔形狀。由於製程的改進，我們已經可以將薄膜的殘餘應力和楊氏係數降低至

Generating Unconventional Spin‐Orbit Torques With Patterned Phase Gradients in Tungsten Thin Films
Advanced Materials, EarlyView.ABSTRACT A key aim in spintronics is to achieve current‐induced magnetization switching via spin‐orbit torques without external magnetic fields. For this, the focus of recent work has been on introducing controlled lateral gradients across ferromagnet/heavy‐metal devices, giving variations in thickness, composition, or interface quality.
