摘要：

P-GaN/n-InGaN/n-GaN double-heterostructure (DH) blue-light-emitting diodes LEDs were fabricated successfully for the first time. The output power was 125 muW and the external quantum efficiency was as high as 0.22% at a forward current of 20 mA at room temperature. The peak wavelength and the full width at half-maximum (FWHM) of the electroluminescence (EL) were 440 nm and 180 meV, respectively. This value FWHM of was the smallest ever reported for blue GaN LEDs.
