中文摘要 在此研究中,成功製作了具有0.28英寸InGaN的藍色micro-LED顯示器,該顯示器具有256像素密度和100 μm的間距。 厚的Ti / Al / Ti / Au內連金屬沉積在n型氮化鎵(n-GaN)區域上,以降低互連電阻。 與傳統金屬相比,具有互連金屬的micro-LED陣列具有更好的電性能一致性。 在全點亮模式下在1mA電流注入下測得的micro-LED的輸出功率、正向電壓和外部量子效率分別為0.8 mW,3.0 V和10%。 該技術具有將基於InGaN的LED與量子點集成在一起的潛力,可用於全彩應用。
英文摘要 A 0.28-inch InGaN-based blue micro-LED display with 256 pixel-per-inch resolution and a pitch of 100 μm was successfully fabricated in this study. A thick Ti/Al/Ti/Au interconnection metal was deposited on the n-type gallium nitride (n-GaN) region to reduce the interconnection resistance. The micro-LED array with interconnection metal exhibits better electrical property consistency as compared with that of the traditional one. The output power, forward voltage, and external quantum efficiency of micro-LED, which measured under 1-mA current injection with the full lighting mode, are 0.8 mW, 3.0 V, and 10%, respectively. This technique has the potential to integrate InGaN-based LEDs with quantum dots for full-color applications.
