Abstract: A method of arranging nanocrystals is provided, which includes a first process of putting barium titanate nanocrystals and/or strontium titanate nanocrystals, and a nonpolar solvent into a container, a second process of collecting a supernatant liquid including the barium titanate nanocrystals and/or the strontium titanate nanocrystals from the container, and a third process of immersing a substrate having an uneven structure into the supernatant liquid, and pulling up the substrate so as to coat the surface of the uneven structure with the supernatant liquid by using a capillary phenomenon, and to arrange the nanocrystals on the uneven structure.
