LIGHT EMITTING DEVICE CAPABLE OF GENERATING LIGHT WITH MULTI-FREQUENCIES OR MONO-FREQUENCY REDUCING PIEZOELECTRIC POLARIZED LIGHT DUE TO STRESS AND A MULTI-FREQUENCY LIGHT GENERATION METHOD

摘要

PURPOSE: A light emitting device and a multi-frequency light creating method are provided to suppress the generation of piezoelectric polarized light, thereby increasing optical efficiency of a wavelength of 500nm or longer.;CONSTITUTION: A first nitride semiconductor layer(13) is deposited on a substrate(10). A nano light emitting array(14) is located on the first nitride semiconductor layer. A plurality of nano light emitting parts(18) is arranged on the nano light emitting array. The nano light emitting part includes a base part(20), a first active layer(25), and a second nitride semiconductor layer(30). A dielectric pattern part is placed between the multiple nano light emitting parts.;COPYRIGHT KIPO 2012
