中文摘要
9312468夏皮罗这项理论和计算研究是由本科生机构研究和本科生研究增强项目资助的。多相互作用分子动力学模拟技术和计算机可视化技术将用于研究:(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-团簇碰撞的破碎特性及其对原子间势的敏感性;(3)能量在每原子电子伏特到千电子伏特范围内的团簇撞击引起的材料改性和薄膜沉积效应;(4)液态合金靶材的同位素溅射效应;(5)合金靶溅射过程中的二聚体喷射;(6)碱卤化物表面高能离子轰击后的碰撞去激发效应;(7)单离子和簇离子轰击引起的表面形貌效应的差异。这项工作将在富勒顿的加州州立大学进行,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。该研究将扩展对离子表面和团簇表面碰撞现象的基本认识,指导未来的实验工作,并吸引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. %%% ***
