Abstract:
1. A method of manufacturing a quantum dot array having a plurality of columnar parts including a quantum dot on a substrate, the method comprising: a first step of obliquely vapor-depositing a material constituting a first barrier layer to become an energy barrier against the quantum dot with respect to a surface of the substrate, so as to form a plurality of the first barrier layers; a second step of obliquely vapor-depositing a material constituting the quantum dot with respect to the surface of the substrate, so as to form the quantum dots on the respective first barrier layers; and a third step of obliquely vapor-depositing a material constituting a second barrier layer to become an energy barrier against the quantum dot with respect to the surface of the substrate, so as to form the second barrier layers on the respective quantum dots.
