| 抄録: | We have shown that hole mobilities of a wide variety of organic thin films can be estimated using a steady-state space-charge-limited current (SCLC) technique due to formation of Ohmic hole injection by introducing a very thin hole-injection layer of molybdenum oxide (MoO_3) between an indium tin oxide anode layer and an organic hole-transport layer. Organic hole-transport materials used to estimate hole mobilities are 4,4',4"-tris(N-3-methylphenyl-Nphenyl-amino)triphenylamine (m-MTDATA), 4,4',4"-tris(N-2-naphthyl-N-phenylamino)triphenylamine (2-TNATA), rubrene, N,N´-di(m-tolyl)-N,N´-diphenylbenzidine (TPD), and N,N´-diphenyl-N,N´-bis(1-naphthyl)-1,1´-biphenyl-4,4´-diamine (α-NPD). These materials are found to have electric-field-dependent hole mobilities. While field dependence parameters(β) estimated from SCLCs are almost similar to those estimated using a widely used time-of-flight(TOF) technique, zero field SCLC mobilities (μ_0) are about one order of magnitude lower than zero field TOF mobilities. |
