摘要

实验表明，CVD生长方法可以使碳纳米管(CNTs)倾向于在镍催化剂薄膜的划痕区生长。我们还发现，在玻璃上涂覆的CaF/ sub2 /膜表面粗糙。因此，以Ni为催化剂，在CaF/sub 2/2包覆的钠碱玻璃上生长CNTs。生长温度极低，约为440/spl℃。CaF/sub 2/2夹层也增强了碳纳米管玻璃的粘附力。对其电子发射特性的研究表明其具有良好的应用前景。

Low temperature carbon nanotube growth on Ni-CaF/sub 2/ 2 coated sodalime glass substrate using thermal CVD method

Our experiments show that carbon nanotubes (CNTs) are inclined to grow at scratched regions of Ni catalyst film on glass substrate with CVD growth method. We also find that CaF/sub 2/ film coated on glass has a rough surface. So CNTs are grown on CaF/sub 2/2 coated sodalime glass using Ni as catalyst. Very low growth temperature of about 440/spl deg/C is achieved. CaF/sub 2/2 interlayer also enhances CNT-glass stickup forces. Investigation of its electron emission property reveals its good potential for FED applications.
