Method of arranging nanocrystals, method of producing nanocrystal structure, nanocrystal structure formation substrate, and method of manufacturing nanocrystal structure formation substrate

A method of arranging nanocrystals, comprising:

• 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 the substrate up, so as to coat a surface of a recessed portion of the uneven structure with the supernatant liquid by using a capillary phenomenon, and arrange the nanocrystals along the recessed portions of the uneven structure,
• wherein the uneven structure has a line and space structure on which a straight or curved recessed portion is formed, and/or which has dot-shaped recessed portions, and
• the shortest width and a depth of the recessed portions are 2.3 μm to 1 mm.
