Title:
BLACK PHOSPHORUS-LIKE ULTRA-THIN BISMUTH NANO-SHEET MODIFIED COMPOUND FILM AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2020/082223
Kind Code:
A1
Abstract:
A black phosphorus-like ultra-thin bismuth nano-sheet modified compound film and a preparation method therefor. The compound film comprises a base film and a black phosphorus-like bismuth nano-sheet intercalation in the base film. Realizing large-scale synthesis of a black phosphorus-like two-dimensional bismuth material and control of physical properties of the material provides a viable path for industrial use of a black phosphorus-like bismuth material for controlling physical properties of materials such as magnetism and semiconductivity, expanding the field of use for metallic bismuth.
