This chapter mainly describes the related work of ambipolar field-effect transistors based on the bilayer structure. The semiconductor materials mainly focus on organic small molecules and polymers, and some bilayer structures based on organic–inorganic hybrid materials are also involved. The internal mechanism of ambipolar properties in devices is explained. The directions for development and device challenges are described and discussed.
This chapter mainly describes the related work of ambipolar field-effect transistors based on blend structures. The semiconductor materials mainly focus on organic small molecules and polymers, and some blend structures based on new materials, such as carbon nanotubes and two-dimensional materials, are also involved. The internal mechanism of ambipolar properties in devices is explained. The direction of development and challenges for the devices are described and discussed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
