Abstract

Abstract: Phase transitions show large responses in physical properties including electrical conductivity changes caused by thermodynamic parameter control or by external stimuli. Thus, an element that shows electronic phase changes in response to input signal may help to provide efficient electronic devices. Strongly correlated electron systems such as Mott insulators are promising candidates for this purpose because they exhibit a large number of electronic phase transitions. Recently, much progress has been made in phase-transition transistors based on organic Mott insulators. In this paper, we review organic transistors that exhibit an insulator-to-metal or an insulator-to-superconductor transition induced by external stimuli such as electric fields, strain, and light.
