Ambipolar inverters with natural origin organic materials as gate dielectric and semiconducting layer

Thin film electronics fabricated with non-toxic and abundant materials are enabling for emerging bioelectronic technologies. Herein complementary-like inverters comprising transistors using 6,6′-dichloroindigo as the semiconductor and trimethylsilyl-cellulose (TMSC) films on anodized aluminum as bilayer dielectric layer are demonstrated. The inverters operate both in the first and third quadrant, exhibiting a maximum static gain of 22 and a noise margin of 58% at a supply voltage of 14 V. (© 2015 WILEY-VCH Verlag GmbH &Co.
