Understanding of the role of defects will therefore be important to improve the transport performances of organic field-effect transistors in spite of increases in defect scattering.
In the case of temperatures at or above room temperature, the mobility decreases with increasing temperature, which indicates that defect scattering is a more dominant effect as temperature increases [9].
While the loss of regioregularity of P3HT and coplanar thiophene orientation increases the effective defect scattering and decreases mean free path for the charge carriers resulting in lower conductivity and mobility [9], carrier concentrations may actually be increasing at higher temperatures.
