Semitransparent conductive carbon films synthesized by sintering spin-coated sp3-based network polymer

Abstract

We synthesized semitransparent conducting thin films of amorphous carbon from sp3-rich network polymer. The films showed a reasonable optical transparency (58–73% transmission in the wavelength range of 380–2200 nm), a low electric resistivity (6.7 × 10−3 Ω cm), and durability against corrosive chemical reagents. The sintering of the amorphous films results in the formation of a carbon honeycomb lattice in the films.
