摘要

Low-operating-voltage organic inverters using bilayer cross-linked poly(4-vinylphenol)/Al2O3 dielectrics were fabricated on polyimide substrates. The flexible inverters could be operated at a supply voltage of as low as 2 V and achieve a gain of over 50 at 2 V. The organic inverters exhibited good mechanical and electrical stabilities after 104 times of bending due to the superior microstructural stabilities of the organic semiconductors, as confirmed by in situ 2D grazing incidence X-ray diffraction (GIXRD). Analysis of GIXRD spectra showed that the variation in the width of the diffraction peak was less than 1.5% after different bending times. The proposed inverters maintained stable gains of above 50 after 104 times of bending and had a maximum transition voltage shift of 0.31 V during the bending process. These findings imply that our inverters could be commercially applied to low-voltage flexible electronics.
