Abstract:

The goal of this project was to produce and characterize improved organic ferroelectric materials with emphasis on improving the response time and sensitivity. We demonstrated 300-fold improvements in the mobility of photorefractive polymer composites by identifying and mitigating the dipolar disorder mobility-reducing mechanism endemic to organic photorefractive materials and choosing transport agents that were relatively insensitive to this mechanism. We also synthesized dendrimers with design features further reducing dipolar disorder and also the significant van der Waals disorder for use in improved-speed photorefractive composites.
