摘要：

Three kinds of different diameter carbon nanotubes(CNTS) films deposited on aluminum sheets by electrophoretic deposition method. Scanning electron microscopy was used to observe the surface morphology of the films. The field emission properties of the films were tested by using a diode structure. The turn-on field for 8nm diameter CNTs film was 0.8V/mu m and the current density of 5200 mu A/cm2 was obtained at 2.3V/mu m. While corresponding data for 15nm and 30nm CNTs films were 1.6V/mu m, 1.4V/mu m, and 2200 mu A/cm2, 850 mu A/cm2 at 3.0V/mu m respectively. The deposited film with 8nm diameter CNTs appeared excellent emission properties.
