Abstract
Provided are a nanostructure and an optical device including the nanostructure. The nanostructure is formed on a two-dimensional material layer such as graphene and includes nanopatterns having different shapes. The nanopatterns may include a first nanopattern and a second nanopattern and may be spherical; cube-shaped; or poly-pyramid-shaped, including a triangular pyramid shape; or polygonal pillar-shaped.
Claims9
A method of manufacturing a nanostructure, the method comprising:
- preparing a solvent in which a block copolymer is dissolved;
- adding a metal precursor to the solvent;
- and
- reducing the metal precursor to a plurality of first nanopatterns and a plurality of second nanopatterns, wherein one of a shape and a size of the plurality of second nanopatterns is different from the one of a shape and a size of the plurality of first nanopatterns, by adding a reducing agent to the solvent.
A method of manufacturing a nanostructure, the method comprising:
- forming a metal seed;
- adding a precursor of nanopatterns and a direction indicator to a solution comprising the metal seed;
- and
- forming a plurality of first nanopatterns and a plurality of second nanopatterns, wherein one of a shape and a size of the plurality of second nanopatterns is different from the one of a shape and a size of the plurality of first nanopatterns, by reducing the precursor.
