Abstract

Bistable nonvolatile memory devices with resistive switching characteristics were fabricated based on polyurethane (PU) doping with single-wall carbon nanotubes (SWCNTs). It has been demonstrated that the addition of SWCNTs in PU layer could enlarge the ON/OFF current ratio from 10 2 –10 4 and keep a long retention time over 9 h. Besides, the increase of SWCNTs and charge traps induced by SWCNT reduced the current in OFF state and enhanced the memory window significantly. Furthermore, the resistive switching behavior of indium tin oxide/PU + SWCNTs/aluminum device was attributed to the formation and breakdown of SWCNTs percolated network structure in the PU composites.
