ZnBi ZnBi Layered ZnBi ZnBi nanosheet and method thereof

摘要

The present invention relates to a layered AZnBi (where A is any one of K, Na, and Li), a layered ZnBi, ZnBi nanosheet, and a method for manufacturing the same. The present invention is to overcome the structure of the mother phase, which is a limitation of the existing two-dimensional material research, and prepares a layered KZnBi, NaZnBi, LiZnBi through crystal structure transition using ion insertion, and uses this to form ZnBi that does not exist in nature Layered structures and ZnBi nanosheets can be prepared. The layered compound and nanosheet of the present invention have excellent thermoelectric properties and can be used as thermoelectric materials in place of Bi ₂ Te ₃ -based materials and PbTe-based materials, and can also be applied as magnetic semiconductors due to ferromagnetic properties.
