Abstract

Flexible hetero-nanowire electronics: A simple solution process has been developed for the first time to fabricate macroscopic flexible, ordered Au-Te hetero-nanowire film electronics with tunable resistance from MΩ to Ω at room temperature (see the Figure). Nanowire films with an electrical conductivity as low as 10,000 S cm(-1) and a sheet resistance of 15Ω sq(-1) can generate reliable interconnections for light-emitting diode (LED) arrays. The Au-Te hetero-nanowire films remain conductive after bending 6000 times with a maximum bending radius of 2.0 mm without any obvious degradation.

Keywords: conductivity; flexible electronics; heteronanowires; nanowire films; self-assembly.
