Carbon nanotubes (CNTs) have been explored in nanoelectronics to realize desirable device performances. Thus, carbon nanotube network field-effect transistors (CNTNFETs) have been developed directly by means of alcohol catalytic chemical vapor deposition (ACCVD) method using Co-Mo catalysts in this work. Various treated temperatures, growth time, and Co/Mo catalysts were employed to explore various surface morphologies of carbon nanotube networks (CNTNs) formed on the SiO2/n-type Si(100) stacked substrate. Experimental results show that most semiconducting single-walled carbon nanotube networks with 5–7 nm in diameter and low disorder-induced mode (D-band) were grown. A bipolar property of CNTNFETs synthesized by ACCVD and using HfO2as top-gate dielectric was demonstrated. Various electrical characteristics, including drain current versus drain voltage(Id-Vd), drain current versus gate voltage(Id-Vg), mobility, subthreshold slope (SS), and transconductance(Gm), were obtained.
