The graph reveals that the mobility in polycrystalline OFETs is comparable to that of a-Si whereas mobility in rubrene-based OFETs ( 20 40 cm 2 / ( V�s ) ) approaches that of best poly-silicon devices.
12.
OFETs employing many aromatic and conjugated materials as the active semiconducting layer have been reported, including small molecules such as rubrene, tetracene, pentacene, diindenoperylene, perylenediimides, tetracyanoquinodimethane ( TCNQ ), and polymers such as polythiophenes ( especially poly ( 3-hexylthiophene ) ( P3HT ) ), polyfluorene, polydiacetylene, poly ( 2, 5-thienylene vinylene ), poly ( p-phenylene vinylene ) ( PPV ).
