系统地研究了 c 轴取向外延 Sr2Rh1−xRuxO4 (0⩽x⩽1) 薄膜的结构和电学特性。在温度梯度 (LaAlO3)0.3(Sr2AlTaO6)0.7 基板上制造成分扩散膜,以快速优化具有每种成分 (x) 的高质量晶体膜的生长温度。观察到异常的 c 轴长度对 x 的依赖性,并且伴随着电特性的明显变化,即金属-绝缘体-金属转变。
Structural and electrical properties of c-axis oriented epitaxial Sr2Rh1−xRuxO4 (0⩽x⩽1) films were systematically investigated. The composition-spread films were fabricated on a temperature gradient (LaAlO3)0.3(Sr2AlTaO6)0.7 substrate to quickly optimize the growth temperature for a high-quality crystalline film having each composition (x). An anomalous c-axis length dependence on x was observed, and it was accompanied by a distinct change in electric property, that is, a metal–insulator–metal transition.
