vs plots for (a) high MW film , (b) medium MW film , and (c) low MW film at room temperature. The thickness of the films is indicated in the plots. The solid lines are fits to the data points using Eq. (1). The dashed lines are fits using Eq. (2). The inset in each figure shows the vs plot of the thicker film device before any correction for the voltage.
(a) Arrhenius plots of vs of the different MW films. Square: High MW film , circle: medium MW film , triangle: low MW film . (b) The temperature dependence of in the low MW film.
Number average molecular weight (MW), polydispersity (PDI), and regioregularity (RR) of samples used in this study. Included also are the measured hole mobility at room temperature and activation energy of the samples in diodes. The electric-field coefficient is included for the low MW film.
