Title:
LAYERED ZNBI, ZNBI NANOSHEET, AND PREPARATION METHODS THEREFOR
Document Type and Number:
WIPO Patent Application WO/2019/151643
Kind Code:
A1
Abstract:
The present invention relates to layered AZnBi (wherein A is any one of K, Na, and Li), layered ZnBi, a ZnBi nanosheet, and preparation methods therefor. The purpose of the present invention is to overcome the structure of a parent phase, which is a limit in the existing research on two-dimensional materials. Layered KZnBi, NaZnBi, or LiZnBi can be prepared through crystal structure transition using ion insertion, and a ZnBi layered structure and a ZnBi nanosheet, which are not present in nature, can be prepared using the layered KZnBi, NaZnBi, or LiZnBi. The layered compound and nanosheet of the present invention have excellent thermoelectric characteristics, and thus can be utilized as a thermoelectric material in substitute for a Bi2Te3-based material and a PbTe-based material, and can also be applied as a magnetic semiconductor due to ferromagnetic characteristics.
