Outline of Final Research Achievements |
The purpose of this study is to understand atomic-scale crystal growth mechanisms from a process of crystal growth at a solid-liquid interface observed by high-speed liquid-environment FM-AFM. In this study, we have obtained the following results. (1) We built a high-speed liquid-environment FM-AFM and demonstrated that an atomic-resolution images can be imaged with 2 sec/frame. (2) We revealed that the imaging mechanism of hydration structures by 3D force distribution measurements using FM-AFM by comparing between experimental and simulated 3D force distribution images. (3) We found the suitable solution for atomic-resolution imaging of a BaF2 crystal in liquids to observe its crystal growth process. (4) We also found the suitable solution for atomic-resolution imaging of an acetaminophen crystal (medical organic compounds) to observe its phase transition process from metastable to stable phase.
