The crosslinking technique forms a PFB/F8BT bilayer with a well-defined interface, and was shown to have a negligible effect on the transport properties as well as the PL and EL emission spectra of the PFB [61], Single-layer, PFB-only and polymer blend LEDs were produced by spin coating 170-nm films from common chloroform solution onto a PEDOTPSS / ITO substrate. For all devices, cathodes were formed by thermal evaporation of Ca (60 nm) and encapsulated with a thick A1 overlayer. 

Current-voltage characteristics of ITO/HIL/NPB/Ag devices using different HIL materials. The HIL are ITO, Au, CuPc, and PEDOTPSS. The solid line is the theoretical trap-free SCLC of NPB. (From Tse, S.C. et al., /. Appl. Phys., 100,063708,2006. With permission.)... 

Hence, r is equal to 1 if the hole injection efficiency is 100%, and the contact can be viewed as truly ohmic. On the other hand, t) should be less than 1 if the contact is Schottky. Figure 3.24 shows t) (solid squares) vs the nominal hole injection barrier at a field strength f=0.1MV/cm. The open circles are the ratios of mobilities derived from DI experiments (Xdi to the TOF-derived hole mobilities p. Moreover, the open triangles are ratios of AS-derived mobilities Pas to the average hole mobilities derived from TOF For the ohmic contact of PEDOTPSS/MTDATA, rj 1 and the hole injection approaches an efficiency of nearly 100%. Meanwhile, the injection efficiency for NPB is lowered to about 70%, but the nominal hole mobilities derived from Dl and AS reach 90% and 100% of the TOF-derived mobility value respectively. For the contact of TPD, the injection efficiency and the nominal hole mobilities are less than 80%. Therefore, PEDOTPSS forms the worst contact with TPD among those PA compounds. 

The hole injection properties of PA-based compounds were investigated and cross-compared by V, DISCLC, and AS measurements. We demonstrate that PEDOTPSS can act as an excellent hole injection material for PA compounds... 

Applications of PEDOT PSS anode in D1 experimenfs reveal currenf fran-sients with a cusp in all PA compounds. Meanwhile, a well-defined minimum can be observed from the plot of frequency-dependenf capacifance in AS measurement. Thus, the results from DISCLC and AS are entirely consisfent with the V results, which by themselves indicate that the contact between PEDOTPSS and PA compounds is very close to ohmic. The hole mobilities of MTDATA, NPB, and TPD could also be defermined from DISCLC and AS techniques. Those mobilities are in good agreement with the TOP measurement. In addition, both injection efficiency (q) and mobilities ratio are reduced due to the injection barrier increase, and indicate that the hole current of TPD still exhibits the injection-limited behavior.
