説明

<jats:p> The electric field effect in YBa<jats:sub>2</jats:sub>Cu<jats:sub>3</jats:sub>O<jats:sub> <jats:italic>y</jats:italic> </jats:sub> (YBCO) thin film was investigated by means of drain-current modulation measurements on Al/(100)SrTiO<jats:sub>3</jats:sub>/(001)YBCO metal-insulator-superconductor field-effect transistors (MISFETs) in the normal state. Sufficient current modulation was obtained in every specimen without exception. Moreover, even an YBCO channel with a semi-insulating phase could be changed to a conductive state by the field effect. The semiconductor band model explained the observed electric field effect semi-quantitatively. </jats:p>
