CASIMIR力量 是來自於量子真空下的產物,當尺寸趨向奈米或微米時CASIMIR力量就愈趨重要,為了要精準量測到CASIMIR力量,我們將使用高真空短同調光源干涉儀去精準測量, CASIMIR力量在金屬球與半導體之間的關係. 同時間,實驗數據與 Lifshitz 理論的比較也會在此討論. 此結果可以幫助我們找到在微機電系統中找到應用

 

A dynamic measurement of the Casimir force between a gold coated sphere and Si plate performed by using a high vacuum based short coherence light source interferometer will be presented. The comparison of results with Lifshitz theory will be discussed. The results will find application in  the design of MEMS (Micro Electro-Mechanical Systems).
