The study presents the dynamics of solid-state dewetting of silver (Ag)-film annealed in N₂ ambient, analyzed by atomic force microscopy and scanning electron microscopy. Varying the annealing parameters (i.e. temperature and time) and Ag-film thicknesses were taken into account, to determine their effect over the solid-state dewetting of Ag-films. Several morphological evolutions from nanohole to the presence of metastable nanorings were observed. It was determined that structures annealed at high temperature (≥900 C) and/or time (≥2 h) results in formation of metastable nanorings and whose geometrical aspects and population grew with increasing film thickness. Possible applications of the structures for fabrication of silicon nanowire arrays and photo-emitters are briefly described.

该研究展示了在 N ₂环境中退火的银 (Ag) 膜的固态去湿动力学，通过原子力显微镜和扫描电子显微镜进行了分析。改变退火参数（即温度和时间）和银膜厚度被考虑在内，以确定它们对银膜固态去湿的影响。观察到从纳米孔到亚稳态纳米环的几种形态演变。确定在高温（≥900℃）和/或时间（≥2h）下退火的结构导致亚稳态纳米环的形成，其几何方面和数量随着膜厚度的增加而增长。简要描述了用于制造硅纳米线阵列和光电发射器的结构的可能应用。
