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
