Abstract
The electric field effect in YBa2Cu3O y (YBCO) thin film was investigated by means of drain-current modulation measurements on Al/(100)SrTiO3/(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.Keywords
