The authors have fabricated field-effect transistors (FET) using 'Durham' route polyacetylene as the active semiconductor. The devices are constructed as MIS structures, with silicon dioxide as the insulator layer between the gate and the polyacetylene. The device behaves as a p-channel enhancement (normally off) FET. For the device geometry presented, the channel conductivity may be modulated by a factor of greater than 2000. The carrier channel mobility and the device transconductance have been determined to be 9*10-6 cm2 V-1 s-1 and 2.5 nS respectively.
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.
