Abstract

Field-emission (FE) characteristics of different photolithographically patterned carbon nanotubes (CNTs) films have been studied. The total FE current is the highest value [2.8 mA (${\sim}$106 mA/$cm^2$) at 7.5 V/${\mu}m$] in patterned CNTs film with the window size of 60 ${\mu}m$ ${\sim}$ 60 ${\mu}m$ and the spacing of 120 ${\mu}m$. It was found that the total widow area is more important factor for the total FE current than the total window length. The contact resistance between CNTs and substrate would be a crucial factor for detachment of CNTs from the substrate.
