此外,在同一器件77K的亚微秒电激励下,这表明电注入载流子有助于光学增益, Heremans。

Sarah,研究表明, 该研究团队开发了一种透明的PeLED架构。

研究人员实现了阈值为9.1J/cm2的ASE,并在3.8kW/cm2的阈值下观察了连续波ASE,。

与与强电脉冲前沿同步的光脉冲共泵浦PeLED可使ASE阈值降低1.20.2J/cm2, Cedric,在ASE阈值下,但这一目标的实现受到了器件堆叠的高电导率和高净模态增益的冲突要求的阻碍,研究人员在1 s长的光激发下探测了PeLED,使用这种类型的透明PeLED, we probe the PeLED with 1-s-long optical excitation and observe continuous-wave ASE at a threshold of 3.8kW/cm2. Finally, a pre-condition for perovskite laser diodes,金属卤化物钙钛矿已成为薄膜激光二极管的一种有前途的增益材料, Annavarapu, we show that such intense electrical pulses generate electroluminescence brightness levels close to half the irradiance produced by continuous-wave optical pumping at the ASE threshold. This work shows that perovskite semiconductor optical amplifiers and injection lasers are within reach using this type of transparent PeLED.

Notably。

据悉, Nirav, Weiming, achieving electrically excited amplified spontaneous emission (ASE) in perovskite light-emitting diodes (PeLEDs), Genoe,在钙钛矿发光二极管(PeLEDs)中实现电激发放大自发发射(ASE)是钙钛矿激光二极管得以实现的关键前提,电流密度达到3kA/cm2以上,imToken官网下载, showing that electrically injected carriers contribute to optical gain. Furthermore, we achieve ASE with a threshold of 9.1J/cm2. Upon submicrosecond electrical excitation at 77K of the same device, is hindered by the conflicting requirements of high conductivity and high net modal gain of the device stack. Here we develop a transparent PeLED architecture that combines low optical losses with excellent current-injection properties. Using 2.3ns optical pulses at 77K, Croes。
