Single electron occupied quantum dot and magnetic control method thereof

摘要

The present invention relates to a single electron occupied quantum dot and a magnetic control method thereof, and more particularly to a quantum dot nanoparticle including a single electron at a quantized energy level of a conduction band and a magnetic control method thereof. The magnetic control method of a quantum dot according to the present invention can control the magnetization of the quantum dots by controlling the chemical reaction time of the quantum dots so that the quantized energy level in the conduction band of the quantum dots can be filled with a single electron, It is effective. Also, since the quantum dots include the mothiol ligand, the n-type doping of the quantum dots can be maintained and the ligand substitution can be easily performed at the same time as compared with the conventional thiol ligands.
