- 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 1.35mA/cm(2) at 3.25 V/mu m and low turn-on field of 2.2 V/mu m at 100 mu A/cm(2). Acetone can be used as an efficient developer to form patterns and to remove the organic residues in patterns, simultaneously. (C) 2010 Elsevier B.V. All rights reserved.
