제목 Structure, Interface and Nonvolatile Memory Characteristics of a High Temperature Polyimide Containing Anthracene Moieties
초록 A high temperature polyimide (PI) bearing anthracene moieties, 6F-HAB-AM PI, was synthesized. The PI exhibits excellent thermal stability up to 400 °C. This PI is amorphous, but orients preferentially in the plane of the nanoscale thin films. In device fabrications of its nanoscale thin films with metal top and bottom electrodes, no diffusion of the metal atoms or ions between the PI and electrodes was found. The aluminum bottom electrode, though, had undergone thin oxide layer formation at the surface during fabrication process, which had no critical effect on the device performance. The PI thin film exhibited excellent unipolar/bipolar switching over a voltage range order of ±2 V. Further, the PI-based thin film electronic devices showed repeatable write-read-erase ability with long time reliability and high ON/OFF current ratio in ambient conditions as well as even at temperatures up to 200 °C.
