Stimulated by the discovery of high-TC superconductivity in 1986, band-filling-control of strongly-correlated electron systems have been a persistent challenge for past three decades in condensed matter science. Especially, recent efforts have been focused on electrostatic carrier doping of such materials utilizing field-effect transistor (FET) structures to find novel superconductivity. In this paper, recent results on the development of novel superconducting (SC) organic FETs, such as strain-tunable SC FET and light-controllable SC FET are summarized. The techniques and knowledge described here will contribute to the advances in future superconducting electronics as well as the understanding of superconductivity in strongly-correlated electron systems.
