9312468夏皮罗这项理论和计算研究是在本科院校的研究和研究增强本科生计划资助。 将利用多重相互作用分子动力学模拟技术和计算机可视化技术研究:(1)离子-表面碰撞中的电子激发和非弹性能量损失效应;(2)团簇-表面和团簇-团簇碰撞的碎裂特性及其对原子间势的敏感性;(3)电子伏至千电子伏/原子范围内的能量的团簇撞击引起的材料改性和薄膜沉积效应:(4)来自液态合金靶的同位素溅射效应;(5)从合金靶溅射中的二聚体喷射;(6)碱金属卤化物表面的高能离子轰击后的碰撞去激发效应;以及(7)由单离子和团簇离子轰击引发的表面形貌效应的差异。 这项工作将在位于富勒顿的加州州立大学与加州理工学院的基础和应用科学小组以及国家标准与技术研究所的表面物理小组合作进行。 该研究将扩展对离子-表面和团簇-表面碰撞现象的基本理解,指导未来的实验工作,并使有前途的年轻本科生参与这一过程。 %%% ***
英文摘要
9312468 Shapiro This theoretical and computational research is funded under the Research at Undergraduate Institutions and Research Enhancements for Undergraduates programs. Multiple-interaction molecular dynamics simulation techniques and computer visualization techniques will be used to study: (1) electronic excitation and inelastic energy loss effects in ion-surface collisions; (2) fragmentation properties of cluster-surface and cluster-cluster collisions and their sensitivity to interatomic potentials; (3) material modification and thin-film deposition effects caused by cluster impacts with energies in the electron-Volt to kiloelectron- Volt per atom range; (4) isotopic sputtering effects from liquid alloy targets; (5) dimer ejection in sputtering from alloy targets; (6) collisional de-excitation effects following energetic ion bombardment of alkali-halide surfaces; and, (7) differences in surface topography effects initiated by single-ion and cluster-ion bombardment. This work will be carried out at California State University at Fullerton in collaboration with the Basic and Applied Science Group at Caltech and the Surface Physics Group at the National Institute of Standards and Technology. The research will extend the fundamental understanding of ion-surface and cluster- surface collision phenomena, guide future experiemntal work and involve promising young undergraduate students in the process. %%% ***
