Korean Researchers developed a simple and efficient low-temperature route to prepare metallic nanowires graphene (MN-G) hybrid nanostructures for flexible field emission devices. The idea is to transfer the graphene layer onto an anodic alumina oxide template and then grow vertically aligned gold (Au) nanowires via electrodeposition.
The nanowires length and diameter can be controlled in this method, an also it avoids any high-temperature steps or unconventional lithography procedures. This means that it could be used with flexible and soft substrates. This can lead to completely flexible field emission devices.
