Résumé

Various molecular weight π-conjugated donor-acceptor polymers based on thiadiazole and thiophene units are investigated with respect to nanoscale film morphology and digital memory performance. Interestingly, all polymers reveal excellent n-type digital permanent memory characteristics, which are governed by the combination of Ohmic and trap-limited space charge limited conductions via a hopping process using thiadiazole and thiophene units as charge traps and stepping stones. The digital memory performance is significantly influenced by the film morphology details that vary with the polymer molecular weight as well as the film thickness. A higher population of face-on structure formation, as well as higher molecular weight, provides a wider film thickness window of digital memory operation. Overall, π-conjugated PBTDzTV polymers are suitable for the production of high-performance, programmable n-type permanent memory devices with very low power consumption.
