| 英文摘要 | An emission layer is formed in a p-layer, and an electron reflecting layer and a hole reflecting layer are formed sandwiching the emission layer. Each of the electron reflecting layer and the hole reflecting layer is constituted by a quantum-wave interference layer with plural periods of a pair of a first layer W and a second layer B. Thicknesses of the first and the second layers in the electron reflecting layer are determined by multiplying by an odd number one fourth of a quantum-wave wavelength of electrons in each of the first and the second layers, and each thicknesses of the first and the second layers in the hole reflecting layer are determined by multiplying by an odd number one fourth of a quantum-wave wavelength of holes in each of the first and the second layers. A luminous efficiency of the LED is improved by electron-hole pairs. The structure in which the emission layer is sandwiched by the electron reflecting layer and the hole reflecting layer is an alternative of a structure in which an i-layer is sandwiched by an n-cladding layer and a p-cladding layer. The emission layer can be formed in a p-layer, and the hole reflecting layer can be formed in an n-layer, an n--layer or a p--layer. |
