The authors describe an organic complementary inverter with N,N′‐ditridecyl‐3,4,9,10‐perylenetetracarboxylic diimide as an n‐type semiconductor and pentacene as a p‐type semiconductor. Each transistor of the inverter exhibited high carrier mobility: 1.62 cm 2 /Vs for an n‐type drive transistor and 0.57 cm 2 /Vs for a p‐type switch transistor. The gain of the inverter reached 125. Another inverter using Ta 2 O 5 as a high κ gate dielectric performed well with a gain of 500 and an operation voltage of only 5 V.(© 2008 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
