Abstract
The invention relates to a high temperature superconducting electric field effect device which creates a dual grain boundary on a superconducting thin film and employs it as a channel. The device comprises a substrate, a bottom layer formed on a predetermined region of the bottom layer, a dual grain boundary channel region formed on the bottom layer, a high temperature source and a drain formed at both end portions of the channel region on the substrate, a high temperature superconducting thin film channel layer formed a predetermined region on the source, the drain and the substrate, dual grain boundaries formed on the high temperature superconducting thin film channel layer, and a gate insulating layer formed on the dual grain boundary channel region.
