Abstract
A method of fabricating a metal oxide sheet having a polycrystalline structure includes mixing a metal precursor material, a base material, and distilled water with each other to fabricate a preparation solution; adding an anionic surfactant into the preparation solution to forming a precursor solution; forming metal oxide nanoparticles in the precursor solution, wherein each of the metal oxide nanoparticles comprises a metal cation and an oxygen anion; and fabricating a metal oxide sheet by coupling the metal oxide nanoparticles to each other, wherein, in an aspect of a plane, the metal oxide sheet has a hexagonal shape and a polycrystalline structure.
