Abstract
The charge transporting properties of N, N'-dipheny 1-N, N'-bis(3-methylphenyl)-(1,1'-biphenyl)-4,4'-diamine (TPD), TPD doped with 5,6,11,12- tetraphenylnaphthacene (rubrene), and TPD doped with 4-(dicyanomethylene)-2-methyl-6-(p-dimethylaminostyryle) 4H-pyran (DCM1) were examined by time-of-flight (TOF) technique between 180-300K. The dependence of the mobility on electric field and temperature for undoped and doped TPD was investigated. Reductions in hole mobility shows that both dopants act as hole traps in TPD. Computational results of TPD also account for the effective hole conduction in pristine TPD film.
