摘要：
Aligned carbon nanotube (CNT) films are potential field emitters for large-area flat panel displays. However, the distribution of emission areas in the CNT films is quite nonuniform because of inhomogeneous nanotube growth. which is hard to avoid using the conventional chemical vapor deposition (CVD) method. Here we show that the emission uniformity of CNT films can be improved simply by reducing the film thickness (thinning) or the nanotube density (diluting). The thickness and density of CNT films could be controlled by controlling the CNT growth time and temperature.
