Nonvolatile Memory Device Based on Copper Polyphthalocyanine Thin Films.


ABSTRACT: In this work, we report the fabrication of nonvolatile memory devices based on chemical vapor deposition-grown copper polyphthalocyanine (CuPPc) thin films. The high polymerization degree and crystallinity of the as-obtained films were confirmed by transmission electron microscopy, X-ray photoelectron spectroscopy, and UV-vis studies. It was found that the device with Au/CuPPc/indium tin oxide sandwich structure exhibits good nonvolatile memory performance with a large ON/OFF current ratio of 103 and long retention time of 1.2 × 103 s.
