Abstract:

Stimuli-responsive materials, showing bistable behaviors between two distinct states under external stimuli, can be potentially applied as basic components of modern electrical and electronic devices. 2D hybrid perovskites hold a promise to switch and tune dielectric bistability based on their solid-state phase transitions. Here, strong dielectric enhancements are successfully actualized by virtue of light illumination in a Dion-Jacobson (DJ) type 2D hybrid perovskite, (HDA)(MA)2Pb3Br10 (1, where HDA is 1,6-hexanediammonium and MA is methylammonium). Upon heating, 1 exhibits an ordered-disordered phase transition approximate to 324 K (Tc), accompanying a transition from its low to high dielectric state. Strikingly, its light-induced dielectric constant changes are greatly enhanced with a magnitude up to 250% near the Tc, superior to most traditional inorganic phase transition materials. This process closely relates to the photoexcited dielectric effect that is caused by the interband photo-excitation. Benefitting from the stability of DJ-type perovskite structure, the switching cycles of dielectric enhancement display operational stability with superior anti-fatigue characteristics. As per the knowledge, the findings of this strong dielectric enhancement are unprecedented in the family of 2D DJ-type hybrid perovskites, which will facilitate broad interest in exploiting new stimuli-responsive materials to assemble high-performance smart electronic devices. Dielectric enhancement is actualized by virtue of light illumination in a 2D Dion-Jacobson-type hybrid perovskite, for which the light-induced dielectric constants are enhanced with a magnitude up to 250%. This work facilitates the exploration of new stimuli-responsive materials to assemble high-performance electronic devices. image
