Abstract

Poly N Epoxipropylcarbazole (PEPC) doped by anthracene (An) based diodes were fabricated by centrifugal deposition equipment at different gravity conditions: 1g, 123g, 277g and 1107 g (g = 9.81 m/sec). All devices follow ed three dimension variable range hopping mechanism and therefore different hopping parameters such as Mott characteristics temperature and hoping distance as a function of gravity conditions were estimated and discussed. Characte ristics temperature and hoping distance s are improved for the devices fabricated at higher gravity conditions and the device fabricated at 277g demonstrate s most optimum charge transport response due to improve ment in the order ness of molecular chains in polymer thin film..
