Low-voltage-operating complementary inverters with C60 and pentacene transistors on glass substrates

Organic complementary inverters with C-60 and pentacene thin-film transistors (TFTs) have been fabricated on glass substrate. The inverter operated at low voltages of 1-5 V. The C-60 and pentacene TFTs had high field-effect mobilities of 0.68 and 0.59 cm(2)/V s, and threshold voltage of 0.80 and -0.84 V, respectively. The low threshold voltage enables the low voltage operation of the inverter. (C) 2007 American Institute of Physics.
