Abstract

In this paper, a superlattice hole blocking layer is proposed to reduce the hole leakage problem of AlGaN based deep ultraviolet laser diodes (DUV-LDs). Three kinds of laser diodes with conventional hole blocking layer, double-tapered hole blocking layer and superlattice hole blocking layer are simulated. It is found that the proposed superlattice hole blocking layer can effectively reduce the hole leakage in the n-region, improve the radiative recombination rate, and thus improve the optical and electrical properties of the device.
具有超晶格孔阻挡层的深紫外激光二极管的性能优化
为了解决AlGaN基深紫外激光二极管(duv - ld)的漏孔问题,本文提出了一种超晶格空穴阻挡层。对常规孔阻挡层、双锥形孔阻挡层和超晶格孔阻挡层三种激光二极管进行了仿真。研究发现,所提出的超晶格空穴阻挡层可以有效地减少n区空穴泄漏,提高辐射复合率,从而提高器件的光学和电学性能。
