摘要
The carrier densities of high temperature superconductors （HTSC） can be easily modu-lated by externally applied electric field because of their lower density value than that ofconventional superconductors (e.g.for YBa<sub>2</sub>Cu<sub>3</sub>O<sub>7</sub> （YBCQ）, n≈5×10<sup>21</sup>/cm<sup>3</sup>). Researches onthe superconducting field-effect transistors （SuFET） based on SrTiO<sub>3</sub>, as the gate
