分析了传统的发光二极管所存在的问题,提出了一种新的发光机制——高效隧道再生多有源区发光机制,详细介绍了新型发光管的工作原理,结构和制备工艺.通过理论和测试分析,验证了新机理器件的轴向光强随有源区的数目增加而线性增加的物理思想,实现了在小电流下的高亮度发光.器件在未生长厚电流扩展层的情况下,峰值波长在625nm左右,20mA注入电流下,15°普通封装,轴向光强最大超过5 cd.
This paper analyzes the problems existing in the traditional LEDs, and proposes a new light-emitting mechanism - the light-emitting mechanism of multi-active regions for efficient tunnel regeneration. The working principle, structure and preparation process of the new LED are introduced in detail. The physical idea that the axial light intensity of the new mechanism device increases linearly with the increase of the number of active regions is verified and verified, and the high luminescence at low current is achieved.When the device is not grown with thick current extension layer, the peak Wavelength of about 625nm, 20mA injection current, 15 ° ordinary package, the maximum axial intensity of more than 5 cd.
