Abstract
A two-dimensional perovskite material, a dielectric material including the same, and a multi-layered capacitor. The two-dimensional perovskite material includes a layered metal oxide including a first layer having a positive charge and a second layer having a negative charge which are laminated, a monolayer nanosheet exfoliated from the layered metal oxide, a nanosheet laminate of a plurality of the monolayer nanosheets, or a combination thereof, wherein the two-dimensional perovskite material a first phase having a two-dimensional crystal structure is included in an amount of greater than or equal to about 80 volume %, based on 100 volume % of the two-dimensional perovskite material, and the two-dimensional perovskite material is represented by Chemical Formula 1.
