Nanotechnology plays a crucial role in enhancing the performance and efficiency of FEDs. One of the primary ways it contributes is through the development of nanomaterials for the cathode. Materials like carbon nanotubes (CNTs) and nanowires have shown exceptional field emission properties. These nanomaterials have a high aspect ratio, which means they can emit electrons more efficiently due to the increased electric field at their tips. This results in a more reliable and brighter display.
