Metal nanofilms and their dewetting behaviors are widely investigated due to the applications in science and industry. However, the random rupture in dewetting process makes it difficult to compare between experimental and simulational results, and further clarify the mechanism. Hence, we focus on the discontinuous metal films which can achieve controllable rupture in the dewetting process. Anodic aluminum oxide (AAO) is selected as the substrate to create nanopore-structured silver film to investigate the dewetting mechanisms of discontinuous metal nanofilms under different conditions. The impact of three specific annealing factors on the dewetting process is validated through experiments involving the sputtering of silver nanofilms on AAO surfaces. Furthermore, we propose dimension analysis to make a comparison between experimental and simulated data, which verifies the accuracy of existing molecular dynamics model in the dewetting behavior of discontinous metal nanofilm.

不连续金属膜脱湿行为的分子动力学和实验研究


由于金属纳米薄膜在科学和工业中的应用，金属纳米膜及其去湿行为被广泛研究。然而，去湿过程中的随机破裂使得实验结果和模拟结果难以进行比较，并进一步阐明其机制。因此，我们专注于不连续的金属膜，这些薄膜可以在去湿过程中实现可控的断裂。选择阳极氧化铝 （AAO） 作为基材，形成纳米孔结构的银膜，以研究不同条件下不连续金属纳米膜的去湿机制。通过涉及银纳米膜在 AAO 表面上溅射的实验验证了三种特定退火因子对去湿过程的影响。此外，我们提出了维度分析来比较实验数据和模拟数据，这验证了现有分子动力学模型在不连续金属纳米膜的去湿行为中的准确性。
