Micro⁃LED具有高分辨率、高色域、高稳定性等优点,在近眼显示领域具有广阔的应用前景。然而,Micro⁃LED存在着巨量电致发光检测和巨量金属键合两大技术瓶颈。本文提出了一种单端载流子注入的Micro⁃LED工作模式,并制备了一种基于该工作模式的Micro⁃LED器件,即单注入型Micro⁃LED。通过实验和仿真研究单注入型Micro⁃LED的工作过程,探究其工作机理。研究了单注入型Micro⁃LED在正弦交流电下的电流⁃驱动电压关系、电流⁃驱动频率关系、亮度-驱动频率关系,以及能带的周期性变化规律,并提出单注入型Micro⁃LED的载流子输运模型。最后,展示了单注入模式在垂直结构Micro⁃LED检测领域的应用,为Micro⁃LED检测提供了新思路。
Micro light-emitting diode(Micro-LED), with many advantages such as high-resolution, high color gamut, and high stability, has broad prospects for near-eye display. However, two major technical issues in Micro-LED need to be solved, including mass electroluminescence detection and mass metal bonding. In this work, a working mode for Micro-LED with single-terminal carrier-injection is proposed, and a single-injection type Micro-LED related to the working mode is fabricated. The working process is studied by experiments and simulations in order to explore the working mechanisms. The current-voltage, current-frequency, brightness-frequency relationship and the periodic variation of the energy band of single-injection type Micro-LED under sinusoidal alternating current are studied. Moreover, the carrier transport model of single-injection Micro-LED is proposed. Finally, the application of single-injection mode used in the detection of vertical structure Micro-LED is demonstrated, which provides new ideas for Micro-LED detection.
