High Mobility Ambipolar Charge Transport in Polyselenophene Conjugated Polymers

Zhuoying Chen, Henrik Lemke, Sebastian Albert-Seifried, Mario Caironi, Martin Meedom Nielsen, Martin Heeney, Weimin Zhang, Iain McCulloch, and Henning Sirringhaus, Weinheim (2010)

High mobility ambipolor polymer field-effect transistors based on a series of regioregular polyselenophenes are presented together with their morphological and optical properties. Balanced electron and hole mobilities on the order of 0.03 cm2 V-1 s-1 are observed by employing a simple top-gate/bottom-contact configuration with photolithographically defined gold source/drain contacts. High gain complementary-like voltage inverters are demonstrated based on two identical ambipolar transistors.
