Structural Studies of Small Particles and Surfaces

该研究计划的目标是使用高分辨率电子显微镜（HREM）和理论建模的结合来研究小颗粒和表面。拟议的研究工作集中在两个领域：(i)小颗粒研究和（ii）气体表面效应。小颗粒研究量化了结构波动，表征了颗粒在衬底上的封装和下沉现象。气体表面效应集中在薄膜和小颗粒暴露于低压气体时结构的变化。

The objective of this research program is to study small particles and surfaces using a combination of high resolution electron microscopy (HREM) and theoretical modeling. The proposed research effort focuses on two areas: (i) small particle research and (ii) gas-surface effects. The small particle research quantifies structural fluctuations and characterizes the phenomena of encapsulation and sinking of particles on a substrate. Gas surface effects focus on changes in the structure of thin films and small particles when exposed to low pressure gas.
