Abstract

Using the method of magnetron sputtering from a multicomponent target manufactured by hot pressing of a powder mixture, thin films of a high-entropy CoCrFeNiTi_x alloy on silicon substrates were first obtained. The microstructure and phase composition of these films have been studied. Resistive thin-film elements are made and their electrical resistance is measured at different temperatures. It is shown that the value of the electrical resistance of new resistive elements linearly depends on temperature with the negative temperature coefficient TCR = –4.66 × 10^–5 K^–1.

微电子电阻元件用高熵CoCrFeNiTix合金薄膜

采用磁控溅射的方法，将粉末混合物热压制成多组分靶材，首次在硅衬底上获得高熵CoCrFeNiTix合金薄膜。研究了这些薄膜的微观结构和相组成。制作了电阻薄膜元件，并在不同温度下测量其电阻。结果表明，新型电阻元件的电阻值与温度呈线性关系，负温度系数TCR = -4.66 × 10-5 K-1。
