Our work has been concentrated on both the selective formation of single-walled carbon nanotubes SWCNTs on a surface-modified Si substrate with functional groups, and the fabrication of SWCNT-three-dimensional networks SWCNT-3DNs on complex 3D-structured templates including deep pores and high pillars. In order to grow SWCNTs on a surface-modified Si substrate selectively, a micro-contact printing and a low energy proton beam irradiation were applied, respectively. Field electron emission properties of self-aligned MWCNT-SWCNT hetero-line patterns were also studied. The SWCNT-3DNs were successfully fabricated inside the deep pores of a porous silicon structure as well as over the micro-sized Si pillar arrays on Si substrate.
