Temperature dependence of the hole mobility

Figure 12-27. Temperature dependence of the hole mobility in DPOP-PPV at different electric fields Dale for T= 0 have been obtained by extrapolation. The inset shows the intersection of Arrhenius plots at T()=465 K (Ref. 1831).

Fig. 9 Temperature dependence of the hole mobility of a polyfluorene copolymer inferred from space-charge-limited current measurements on samples of thicknesses 122 nm, 1 pm, and 10 pm. The full curve is an extrapolation to the low carrier density limit using the extended Gaussian disorder model. From [90] with permission. Copyright (2008) by the American Institute of Physics...

In this context it is appropriate to recall the work of Mozer et al. [91] on hole transport in regio(3-hexylthiophene). These authors compared the field and temperature dependencies of the hole mobility measured via the ToF and CELIV methods. Quite remarkably, the temperature dependence deduced from ToF signals plotted on a In p vs scale deviate significantly from linearity while the CELIV data follow a In p law down to lowest temperatures (180 K) (see Fig. 10). The reason is that... 

Fig. 11 Temperature dependence of the hole mobility in PMPSi at different electric fields. Full curves are calculated using the theory by Fishchuk et al. [70], The fit parameters are the width a of the density of states distribution, the activation energy (which is p/2), the electronic exchange integral J, and the intersite separation a.

Fig. 17 Temperature dependence of the hole mobility measured in an FET with (a) pentacene and (b) P3HT as active layers. Parameter Is the gate voltage. Data fitting using the Fishchuk et al. theory in [102] yields values for the mobility and the disorder potential extrapolated to zero electric field and zero carrier concentration. To is the Meyer-Nedel temperature (see text). From [102] with permission. Copyright (2010) by the American Institute of Physics...
