ABSTRACT
With a TiO2 -based photocatalytic approach, both an arbitrary geometry tailoring of single-walled carbon nanotubes (SWCNTs) on various substrates and the conversion of metallic to semiconducting SWCNTs are demonstrated. Taking advantage of the selectivity on the diameter and metallicity of SWCNTs, 100% depletable SWCNT-based field-effect transistors are achieved, with Ion /Ioff improvements up to five orders of magnitude.
