Tunability of Mobility and Conductivity over Large Ranges in Poly(3,3-didodec…

ABSTRACT Semiconducting polymers are currently being considered as active layers in field-effect transistors, in which high charge carrier mobility and low off conductivity are important. For other applications, such as certain spintronic mechanisms, the opposite characteristics are desirable. Blending such polymers with insulating polymers would be expected to lower the mobility. In this pap…
