Transistor Paint: High Mobilities in Small Bandgap Polymer Semiconductor Based on the Strong Acceptor, Diketopyrrolopyrrole and Strong Donor, Dithienopyrrole
A narrow bandgap, strong donor-acceptor polymer semiconductor is presented. This "transistor paint" material exhibits hole mobilities as high as 0.41 cm(2)/Vs. Importantly, the semiconductor yields high reproducible mobility values of 0.28 cm(2)/Vs +/- 0.019 for a range of channel lengths when measured from several transistors on different days.
