Carbon nanotube (CNT) networks have garnered considerable attention for their exceptional electronic properties. The self-assembly of CNT networks presents promising prospects for artificial neural networks, especially for physical reservoirs reliant on random networks [1]. Dai et al. have previously demonstrated extensive CNT networks using chemical vapor deposition (CVD) techniques [2], indicating controable fabrication potential. Additionally, kite-growth [3,4] is effective to elongate the CNT array length suspended in the network [5], further propelling CNT networks in electronics.
This study aims to explore the fabrication of CNT random networks connecting between nano-pillars with assistance of the kite growth process. By optimizing the pillar spacing on quartz substrates, we achieve a balance between longer CNT spans driven by kite growth and shorter CNT spans resulting from capture by closely spaced pillars. This approach streamlines synthesis while enhancing the structural and electronic properties of the CNT networks.
