P3 HT/PMMA双层聚合物电双稳器件的研究
Polymer Bistable Devices Based on Poly(3-hexylthiophene)/Poly(methylmethacrylate) Bilayer Films
摘要
Abstract
P3 HT/PMMA bilayer device was fabricated through layer by layer spin-coating method and the device performance was greatly enhanced comparing with P3 HT and PMMA single layer de-vice. SEM image was taken to study the cross-section morphology of the bilayer film. The current-voltage ( I-V) and current-repeatable times ( I-t) measurements were taken to investigate the per-formance of the devices. The bilayer one has a better ON/OFF ratio about 1 × 103 and the device is quite stable. The fitting of I-V curves was utilized to analyze the charge transport process with the help of the diagram of the energy bands. The results show that the charge trapping-detrapping theory can be used to explain the operating mechanism of the bilayer device.关键词
