Abstract

The authors report on the fabrication of complementary thin-film transistor (CTFT) inverters with pentacene (p type) and ZnO (n type) hybrid channels on rf-deposited Al Ox dielectrics. All deposition processes were carried out on glass substrates at low temperatures (<100 °C). Since our p -channel TFT showed somewhat equivalent field mobility of 0.11 cm2 V s compared to that of the n -channel device (0.75 cm2 V s), the hybrid CTFT inverters were designed with identical dimensions for both channels. The CTFT device demonstrated an excellent voltage gain of ∼21 with a low static power dissipation of ∼1.5 nW at a low supply voltage of 7 V.
