最近在SrTiO 3（STO）衬底上发现的FeSe单晶胞（UC）薄膜的高温超导性在实验和理论上都引起了极大的研究兴趣。这种情况是否可以扩展到其他超导体，对于确定增强的超导机制和进一步提高临界转变温度（Tc）至关重要。在这里，我们成功地制备了单UC FeTe 1-xSex（0.1
Recently discovered high-temperature superconductivity in single-unit-cell (UC) FeSe films on SrTiO3 (STO) substrate has stimulated tremendous research interest, both experimental and theoretical. Whether this scenario could be extended to other superconductors is vital in both identifying the enhanced superconductivity mechanism and further raising the critical transition temperature (T-c). Here we successfully prepared single-UC FeTe1-xSex (0.1
