Stack structure including quantum dot, method of manufacturing the same and light emitting device using the stack structure

摘要

PURPOSE: A lamination structure, a manufacturing method thereof, and a light emitting device applying the same are provided to increase use efficiency of a quantum dot by easily controlling location and size of the quantum dot. CONSTITUTION: A plurality of holes(H1) is formed at one side of a semiconductor layer(10). An under layer(20) is formed on the upper side of the semiconductor layer. The under layer is conformally included along the upper side of the semiconductor layer. A quantum dot(30) is formed at the bottom of the plurality of holes. A graphene layer(40) covering the quantum dot is formed on the under layer. A planarization layer(50) is formed on the graphene layer. The plurality of holes is filled with the planarization layer.
