LIGHT-EMITTING DIODES AND METHODS OF MANUFACTURING THE LIGHT-EMITTING DIODES

摘要

PURPOSE: A light emitting diode and a method for manufacturing the same are provided to form an n-type semiconductor for emitting green light and absorbing blue light on an active layer for generating blue light, and secure a high efficiency green light emitting device. CONSTITUTION: A p-type compound semiconductor layer(130) is formed in the upper part of a substrate(110). An active layer(150) is formed in the upper part of the p-type compound semiconductor layer. An active layer emits blue wavelength light. An n-type oxide semiconductor layer(170) made of zinc oxide is formed in the upper part of the active layer. The n-type oxide semiconductor layer absorbs the green wavelength light to emit the blue wavelength light.
