Abstract
- Multi-wall carbon nanotubes were deposited on the patterned silicon substrates using electrophoretic deposition. The surface images of carbon nanotubes on substrate were observed by scanning electron microscopy. Field emission properties have been tested with a diode structure in a vacuum chamber below 5/spl times/10/sup -4/ Pa. The emission area measured is 1.0mm. Emission current density up to 30mA/cm at an electric field of 8V//spl mu/m has been obtained. Patterned deposition of carbon nanotubes by electrophoresis is a potential method to prepare field emission arrays.
