Organic complementary inverters were fabricated with low-voltage pentacene/SrTiO3 and C60/SrTiO3 field-effect transistors (FETs), without formation of self-assembled monolayer on surface of the dielectric SrTiO3. The inverters showed the highest gain of 18.4 at an operating voltage as low as 3 V, where the pentacene/SrTiO3 and C60/SrTiO3 FETs on the inverters showed hole and electron mobilities of 0.85 and 0.07 cm2/V s with threshold voltages (VT) of −1.1 and −0.2 V, respectively.
