Electronic element with nanomaterial and manufacturing method thereof
View Patent ↗A nanomaterial includes quantum dots having a crystal structure, wherein the quantum dots include an exposed surface in a specific direction, and the exposed surface has a ligand bound thereto.
1. A manufacturing method of a nanomaterial comprising quantum dots, the manufacturing method comprising:
controlling a ratio of an exposed surface of the quantum dots having a crystal structure in a specific direction; and
binding a ligand to the exposed surface,
wherein energy level of the nanomaterial is different depending on the ratio of the exposed surface or an amount of the ligand,
wherein the energy level is adjusted by an electronegativity difference between the exposed surface and the ligand,
wherein the ratio of the exposed surface in the specific direction of the quantum dots having the crystal structure is controlled by adjusting a growth of a crystal through a method of stabilizing a surface energy by binding an arbitrary ligand to a surface which is wanted to be exposed and destabilizing the surface energy by binding an arbitrary ligand to a surface which is not wanted to be exposed while supplying a monomer, which is a constituent material of the quantum dots, and
wherein the quantum dots are formed of two or more components, and the exposed surface is formed of one component.
2. The manufacturing method of claim 1 , further comprising performing an operation of exchanging the ligand with other ligands.
3. The manufacturing method of claim 1 , wherein the ligand includes an ion or molecule selected from the group consisting of an amine-based ligand, a thiol-based ligand, a phosphine-based ligand, a phosphine oxide-based ligand, and combinations thereof.
4. The manufacturing method of claim 2 , wherein the other ligands include a ligand selected from the group consisting of F, Cl, Br, I, 3-mercaptopropionic acid, ethanedithiol, and combinations thereof.
