Yen-Hsi Lin

As a research assistant, I acquired valuable skills and knowledge in polymer science and MEMS

devices. My current research involves the fabrications and structural characterization of polymer thin films and the use of atomic force microscopy to study the structure. I have also studied the mechanical properties of a number of different classes of material surfaces. My research techniques include coating ultra thin polymer films, organic self-assembled monolayers, microprinting, gradient polymer brush, nanoparticle deposition and chemical vapor deposition. I have three years experience in AFM analysis of nanocomposite films (including scanning, fluid, force volume, friction and adhesion measurements).
