Healing defects of metallic structures is an essential procedure for manufacturing and maintaining integrated devices. Current nanocomposite-assisted microhealing methodologies are inadequate for nanoscopic applications because of their concomitant contamination and limited operation accuracy. In this paper, we propose an optically controllable targeted nanohealing technique by utilizing the plasmonic-enhanced photothermal effect. The healing of nanogaps between two silver nanowires (NWs) is achieved by increasing the incident laser power in steps. Partial connection of NWs can be readily obtained using this technique, while near-perfect connection of NWs with the same crystal orientations is obtained only when the lattices on the two opposing facets are matched after recrystallization. This non-contaminating nanohealing technique not only provides deeper insight into the heat/mass transfer assisted by plasmonic photothermal conversion in the nanoscale but also suggests avenues for recovering mechanical, electronic, and photonic properties of defected metallic nanodevices.Healing defects of metallic structures is an essential procedure for manufacturing and maintaining integrated devices.

等离子增强金属纳米结构的靶向纳米修复

修复金属结构的缺陷是制造和维护集成设备的重要程序。当前的纳米复合材料辅助显微愈合方法不适合纳米级应用，因为它们伴随着污染和有限的操作精度。在本文中，我们提出了一种利用等离子体增强光热效应的光学可控靶向纳米修复技术。两条银纳米线 (NW) 之间的纳米间隙的愈合是通过逐步增加入射激光功率来实现的。使用这种技术可以很容易地获得 NW 的部分连接，而只有当两个相对面上的晶格在再结晶后匹配时，才能获得具有相同晶体取向的 NW 的近乎完美的连接。这种无污染的纳米修复技术不仅提供了对纳米级等离子体光热转换辅助的热/质量传递的更深入了解，而且还提出了恢复有缺陷金属纳米器件的机械、电子和光子特性的途径。制造和维护集成设备的基本程序。当前的纳米复合材料辅助显微愈合方法不适合纳米级应用，因为它们伴随着污染和有限的操作精度。在本文中，我们提出了一种利用等离子体增强光热效应的光学可控靶向纳米修复技术。两条银纳米线 (NW) 之间的纳米间隙的愈合是通过逐步增加入射激光功率来实现的。使用这种技术可以很容易地获得 NW 的部分连接，而只有当两个相对面上的晶格在再结晶后匹配时，才能获得具有相同晶体取向的 NW 的近乎完美的连接。这种无污染的纳米修复技术不仅提供了对纳米级等离子体光热转换辅助的热/质量传递的更深入了解，而且还提出了恢复机械、...
