Localized lateral growth of single-walled carbon nanotubes for field-effect transistors by a cobalt-mix-TEOS method

Abstract

Lateral-growth carbon nanotubes (CNTs) were fabricated in a pre-assigned area using an integrated circuit compatible method. In order to synthesize single wall carbon nanotubes (SWNT) for the fabrication of a field-effect transistor (FET), the cobalt-mix-tetraethoxysilane (TEOS) (CMT) solution is proposed. The CMT solution has the unique property of dispersing the cobalt (Co) catalyst well and uniformly embedding it in a predetermined location after the CMT solution has solidified. The lateral growth of bundle-SWNT could be formed in atmospheric chemical vapor deposition (APCVD) with ethanol. (c) 2005 The Electrochemical Society.
