Laser Nanosoldering Boosts Conductivity of Nanoelectrodes

Researchers at Jinan University and the Chinese Academy of Sciences developed a plasmon-enhanced laser nanosoldering technology to increase the electrical conductivity of silver (Ag) nanowires that are fabricated using femtosecond laser direct writing (FsLDW). This technology could provide an efficient, cost-effective way to rapidly produce large-area metal nanoelectrodes and capacitors that are uniform, flexible, and highly conductive. FsLDW is used to build Ag nanowires for engineered patterns in 2D and 3D, and that have submicron resolution. This nanofabrication method offers many advantages, including high resolution, true three-dimensionality, and flexibility. It is widely used in the fabrication of optoelectronic devices. ...
