FIG. 4.

Reciprocal temperature dependence of the charge carrier concentration for PI and PAI films. Solid lines represent Arrhenius linear fits.

Image of FIG. 5.
FIG. 5.

Reciprocal temperature dependence of the charge mobility for PI and PAI films. Lines represent linear Arrhenius and non-linear VFT fits. Fitting parameters for PI: (Arrh. for )  = 1.3 cm2 V−1 s−1,  = 0.75 eV. Fitting parameters for PAI: (VFT for )  = 2.8 × 10−6 cm2 V−1 s−1,  = 0.78,  = 513 K; (VFT for )  = 2.2 × 10−3 cm2 V−1 s−1,  = 4.4, = 430 K.
