Characterization of Dynamic Surface Processes by Atomic Force Microscopy

摘要: Surfaces are actively involved in numerous biological systems as well catalytic reactions. The control of matters at surfaces is also uttermost importance with the advent nanotechnology. A thorough knowledge surface processes would not only help to describe mechanism different reactions or interactions but lead rational design for construction functional systems. Among various characterization techniques, Atomic Force Microscopy (AFM) offers outstanding spatial resolution which enables investigation single molecular level and establishment microscopic models. In this dissertation, AFM used study processes, a focus on dynamics (Chapter 2) dynamic change properties 3 & 4). Chapter 2, configured certain way improve temporal resolution, electrochemical etching gold within nanoshaved self-assembled monolayer investigated. Novel kinetic information obtained demonstrates potential fabrication high-resolution nanoplasmonic structures. 4, monolayers that contain electroactive species construct can alternate their charge states upon applied potential. nanoscale patterns fabricated by nanometer scale explored 3. probe adhesion polyelectrolyte surface, serves model system studying electrostatic interaction between charged substances Microscopic picture interface described based from Dynamic Spectroscopy (DFS).
