    • Disclosed is a quantum-dot LED and fabrication method thereof. The quantum-dot LED includes: a substrate; a n-type semiconductor layer formed on the substrate; an insulator layer formed on the n-type semiconductor layer and provided with a plurality of holes; quantum dots formed by filling the holes; and a p-type semiconductor layer formed on the insulator layer in which the quantum dots are formed. According to the inventive LED, the size and density of the quantum dots are controllable to thereby make the property control of the LED easy. Also, since it can be anticipated that the LED has a high internal quantum efficiency compared with the conventional LED using quantum well, high light emitting efficiency can be obtained.
    • 公开了一种量子点LED及其制造方法。 量子点LED包括:基板; 形成在所述基板上的n型半导体层; 形成在所述n型半导体层上并具有多个孔的绝缘体层; 通过填充孔形成的量子点; 以及形成在其上形成有量子点的绝缘体层上的p型半导体层。 根据本发明的LED,量子点的尺寸和密度是可控的,从而使得LED的性质控制变得容易。 此外,由于可以预期,与使用量子阱的常规LED相比,LED具有高的内部量子效率,因此可以获得高的发光效率。
