TLDR
Organic field-effect transistors have been developed that function as either n-channel or p-channel devices, depending on the gate bias, and can be used as a building block to form low-cost, low-power complementary integrated circuits.Abstract:
Organic field-effect transistors have been developed that function as either n-channel or p-channel devices, depending on the gate bias. The two active materials are α-hexathienylene (α-6T) and C 60 . The characteristics of these devices depend mainly on the molecular orbital energy levels and transport properties of α-6T and C 60 . The observed effects are not unique to the two materials chosen and can be quite universal provided certain conditions are met. The device can be used as a building block to form low-cost, low-power complementary integrated circuits.read more

TL;DR: It is demonstrated that the use of an appropriate hydroxyl-free gate dielectric—such as a divinyltetramethylsiloxane-bis(benzocyclobutene) derivative (BCB; ref. 6)—can yield n-channel FET conduction in most conjugated polymers, revealing that electrons are considerably more mobile in these materials than previously thought.
