QUANTUM DOT ARRAY AND PRODUCTION METHOD THEREFOR, AND DOT ARRAY ELEMENT AND PRODUCTION METHOD THERERFOR

摘要

A production method for a quantum dot array having on a substrate a plurality of columnar units having quantum dots, comprising the step of obliquely vapor-depositing on the surface of a substrate the constituting materials of a first barrier layer working as an energy barrier against quantum dots to form a plurality of first barrier layers, the step of obliquely vapor-depositing on the surface of a substrate the constituting materials of quantum dots to form quantum dots on the first barrier layer, and the step of obliquely vapor-depositing on the surface of a substrate the constituting materials of a second barrier layer working as an energy barrier against quantum dots to form a second barrier layer on quantum dots.
