The present invention relates to a layered GaAs, a method for manufacturing the same, and a GaAs nanosheet peeled from the same, and more particularly, unlike a conventional bulk GaAs, the present invention has a two-dimensional crystal structure and has excellent peelability to peel off in the form of a nanosheet. The present invention relates to a layered GaAs having easy electrical properties and having excellent electrical properties by having a structure in which charge transfer is easy in an in-plane direction.
