Low temperature carbon nanotube growth on Ni-CaF2 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 CaF₂ film coated on glass has a rough surface. So CNTs are grown on CaF₂2 coated sodalime glass using Ni as catalyst. Very low growth temperature of about 440°C is achieved. CaF₂2 interlayer also enhances CNT-glass stickup forces. Investigation of its electron emission property reveals its good potential for FED applications.
