Abstract

We first demonstrate the photorefractive (PR) performances of methyl-substituted poly(triarylamine) (PTAA)-based PR device with chemically modified electrodes (CME) of self-assembled monolayer (SAM) coated indium-tin-oxide (ITO) electrodes. The response time of 11.3 ms was achieved at lower electric field of 20 V μm⁻¹, which was comparable to the response time of high-definition television (HDTV) quality, 16 ms. Our approach will widen the usage of higher mobility materials to photorefractive field and give us more favorable materials to achieve the best performance of photorefractivity in the future.
