Abstract
Photosensitive carbon nanotube (CNT) paste was prepared by 3-roll milling of multi-walled carbon nanotubes (MWNTs), UV-sensitive binder solution, and Ag as filler additives. Arrays of MWNT dots with a diode structure were fabricated by a combination of screen printing method and photolithography using these paste, and acetone utilized as the developer. The MWNT dots were well-defined and the organic binder materials in the dots were partially removed. The MWNT film without a heat treatment showed a high current density of 1.35 mA/cm 2 at 3.25 V/μm and low turn-on field of 2.2 V/μm at 100 μA/cm 2 . Acetone can be used as an efficient developer to form patterns and to remove the organic residues in patterns, simultaneously.
