Patent ID: 7015139

Claim:
A method of fabricating quantum dots, the method comprising: adsorbing a plurality of metalloprotein complexes onto an LB membrane developed on a surface of an aqueous solution to thereby array the metalloprotein complexes in a two-dimensional configuration on the LB membrane at regular intervals, each of the metalloprotein complexes comprising a protein and metal oxide particles contained in a core of the protein; placing the LB membrane having the metalloprotein complexes adsorbed in the two-dimensional configuration at regular intervals thereon on a substrate and burning out the proteins under an inert atmosphere that does not react with the substrate to thereby leave the metal oxide particles arrayed in a two-dimensional configuration at regular intervals on the substrate, the substrate being durable to a temperature higher than the burn-out temperature of the proteins and the substrate having an insulation layer or a semiconductor layer on a surface thereof; and reducing the metal oxide particles arrayed in the two-dimensional configuration at regular intervals on the insulation layer or the semiconductor layer to thereby obtain a plurality of metal atom aggregates arrayed in a two-dimensional configuration at regular intervals on the insulation layer or the semiconductor layer.
