This article describes recent progress in high-temperature superconducting oxide electronics. Notable applications include (i) three-terminal superconducting transistors, (ii) Josephson junctions, and (iii) microwave and optical devices. Critical temperatures Tc higher than 77K are characteristic of oxide superconductors, and most applications are based on this feature. Another feature of this kind of material is the low carrier concentration, which is nearly the same order as that of degenerate semiconductors. A superconducting MIS electric field effect transistor has been obtained by using epitaxial oxide superconductor thin films. This article reviews high-Tc superconductor devices, particularly YBCO-MISFETs.
