The properties and microstructure of (Cr, Fe, V)–(Ta, W) high-entropy films (HEFs) are studied using combinatorial strategies. The compositional library of (Cr_0.33Fe_0.33V_0.33)_x(Ta_0.5W_0.5)_100–x, (0 < x < 100), HEFs are fabricated by cosputtering to discover potential photothermal conversion materials. By verifying points in the compositional library, the structure and property variation according to the atomic content of elements are carefully studied. Results indicate that the films exhibit an amorphous structure when x ranges from 86.9 to 32.5, and high concentrations of Ta and W lead to the formation of a BCC structure in the films. The solar absorptivity of the films peaks at the transitional area from an amorphous to BCC structure. Our research provides an efficient combinatorial technique to discover HEFs with high performance.

伪二元（Cr，Fe，V）-（Ta，W）系统中的高通量筛选太阳热转换膜

使用组合策略研究了（Cr，Fe，V）–（Ta，W）高熵薄膜（HEFs）的性质和微观结构。通过共溅射制造（Cr _0.33 Fe _0.33 V _0.33）_x（Ta _0.5 W _0.5）_{100– x}（0 < x <100），HEF的成分库，以发现潜在的光热转换材料。通过验证组成库中的点，仔细研究了根据元素原子含量的结构和性质变化。结果表明，当x为0时，薄膜显示出非晶结构。范围从86.9到32.5，高浓度的Ta和W导致薄膜中形成BCC结构。薄膜的日光吸收率在从非晶态到BCC结构的过渡区域达到峰值。我们的研究提供了一种有效的组合技术来发现具有高性能的HEF。
