Electronic element with nanomaterial and manufacturing method thereof

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.
