Tensile strain dependent conductivity of Single-Wall Carbon Nanotube Network thin film

Abstract

Deformation of the lattice structure of single-wall carbon nanotubes (SWCNTs) has been known to change its conductivity by changing the band structure. Especially, external strain induced 1% elongatoin of a semiconducting SWCNT latttice has been shown to increase the band gap as mush as 10 %.Here, we investigate teh external strain dependent conductivity of a SWCNT network formed on a stretchable silicone elastomer surface for possible mechanical deformation sensor application.
