Abstract: The disclosure belongs to the field of micro-nano electronic materials, and in particular to a Se-based selector material, a selector unit, and a preparation method thereof. The Se-based selector material is a compound including Ge, Se, and B elements. The chemical formula of the Se-based selector material is (GexSe1−x)1−yByMz, in which the M element is at least one of In, Ga, Al, and Zn, and 0.1≤x≤0.9, 0.02≤y≤0.15, and 0≤z≤0.2. The problems of safety and stability of the existing material selection for the selector are solved by the selector material, the selector unit, and the preparation method thereof provided by the disclosure. In addition, the threshold voltage of the selector device prepared based on the Se-based selector material is adjustable, and the comprehensive performance is good.
