Design and Properties Analysis of a Single-chip White InGaN/GaN LED
LED can not only improve the quality and efficiency of light, but also save energy and reduce environmental pollution. Developing LED industry has great significance for the national economy and the peoples livelihood. In the paper, main methods for fabricating white LED and recent progresses in white LED are studied. And then, a novel single-chip white InGaN/GaN LED is designed. Fanally, the I-V characteristics and optical characteristics of the LEDs are analyzed. Turn-on voltage of the single-chip white light LED is 2.7V and reverse leakage current is 0.18mA at reverse-bias voltage of ISV.The singlechip white LED emits white light as the injection current is from 5mA to 60mA.
