Abstract

A structure including quantum dots formed in a surface control region, a method of forming a structure including quantum dots in a surface control region, a surface-controlled substrate provided with the structure including quantum dots, and a photoelectronic element using the same. The method includes forming multiple surface control layers that differ in etch resistance on a substrate, securing a surface control region on the substrate by forming control patterns having respectively different sizes in the respective surface control layers depending on the etch resistance values through an exposure process, forming the structure including quantum dots in the surface control region by using the plurality of surface control layers as masks, and removing the surface control layers.
