项目摘要

Proposal Title: Adsorbate Mediated Electrodeposition: Experimental and Multiscale Numerical Investigations on Surface Roughness and Shape EvolutionProposal Number: CTS-0135621Principal Investigator:Richard AlkireInstitution:University of IllinoisThe objective of this collaborative effort is to improve understanding of how surface roughness and shape evolution are influenced by trace quantities of solution additives during electrodeposition of metals and alloys. Multiscale simulations of the electrodeposition process including both continuum and non-continuum behavior will be performed. Hypotheses for how additives influence surface roughness evolution will be inferred from large datasets obtained through atomic force microscopy (AFM) measurements carried out in conjunction with high throughput electrochemical cells and well-characterized model additive systems. Hypotheses will be refined through quantitative comparison of these data with multiscale simulations of roughness evolution. Non-continuum phenomena will be modeled by a three-dimensional kinetic Monte Carlo method that simulates how roughness evolution is controlled by additives. Verification experiments that measure shape evolution on surfaces of convoluted geometry will be carried out to test predictions over multiple length scales. This work will lead to a better understanding of processes used in the manufacture of novel structures formed by electrodeposition of metals, alloys and semiconductors.

提案标题：吸附物介导的电沉积：表面粗糙度和形状演化的实验和多尺度数值研究提案编号：CTS-0135621 首席研究员：Richard Alkire 机构：伊利诺伊大学这项合作的目的是加深对金属和合金电沉积过程中微量溶液添加剂如何影响表面粗糙度和形状演化的理解。将进行电沉积过程的多尺度模拟，包括连续介质和非连续介质行为。关于添加剂如何影响表面粗糙度演变的假设将从通过原子力显微镜 (AFM) 测量获得的大型数据集中推断出来，这些测量与高通量电化学电池和充分表征的模型添加剂系统相结合。通过将这些数据与粗糙度演化的多尺度模拟进行定量比较，可以完善假设。非连续现象将通过三维动力学蒙特卡罗方法进行建模，该方法模拟添加剂如何控制粗糙度演化。将进行测量卷积几何表面形状演化的验证实验，以测试多个长度尺度上的预测。这项工作将有助于更好地理解金属、合金和半导体电沉积形成的新型结构的制造工艺。
