A three-dimensional ordered and self-organized semiconductor system emitting highly polarized light in the yellow-orange visible range (580–650 nm) is presented, comprising self-assembled in-plane AlInP wires vertically stacked in regularly spaced columns. More than 200 wires per column without detectable defect formation could be stacked. Theoretical simulations and temperature-dependent photoluminescence provided a benchmark to engineer multilayered structures showing internal quantum efficiency at room temperature larger than comparable quantum wells emitting at similar wavelengths. Finally, proof-of-concept light-emitting diodes (LED) showed a high degree of light polarization and lower surface parasitic currents than comparable quantum well LEDs, providing an interesting perspective for high-efficiency polarized yellow-orange light-emitting devices.

用于极化微米级琥珀色发光二极管的AlInP量子线的三维自组装柱状阵列

提出了一种三维有序且自组织的半导体系统，该系统发出在橙黄色可见光范围（580–650 nm）中的高偏振光，包括垂直堆叠在规则间隔的列中的自组装面内AlInP线。每列可堆叠200多根没有可检测到的缺陷形成的导线。理论仿真和与温度有关的光致发光为设计多层结构提供了基准，该多层结构显示出在室温下的内部量子效率大于在相似波长下发射的可比量子阱。最后，概念验证型发光二极管（LED）与类似的量子阱LED相比，显示出较高的光偏振度和较低的表面寄生电流，
