Efficiency-enhanced AlGaInP light-emitting diodes using transparent plasmonic silver nanowires

Silver nanowire(AgNW) networks have been demonstrated to exhibit superior transparent and conductive performance over that of indium-doped tin oxide(ITO) and have been proposed to replace ITO, which is currently widely used in optoelectronic devices despite the scarcity of indium on Earth. In this paper, the current spreading and enhanced transmittance induced by AgNWs, which are two important factors influencing the light output power, were analyzed. The enhanced transmittance was studied by finite-difference time-domain simulation and verified by cathodoluminescence measurements.The enhancement ratio of the light output power decreased as the Ga P layer thickness increased, with enhancement ratio values of 79%, 52%, and 15% for Ga P layer thicknesses of 0.5 μm, 1 μm, and 8 μm, respectively, when an AgNW network was included in Al Ga In P light-emitting diodes. This was because of the decreased current distribution tunability of the AgNW network with the increase of the Ga P layer thickness. The large enhancement of the light output power was caused by the AgNWs increasing carrier spread out of the electrode and the enhanced transmittance induced by the plasmonic AgNWs. Further decreasing the sheet resistance of AgNW networks could raise their light output power enhancement ratio.     

精细化网络流量分析的作用

络安全问题是现代社会中的重要问题。随着网络技术的发展，网络攻击手段也日趋复杂和隐蔽，传统的网络安全防护方法已经无法满足对抗各种恶意攻击的需求。而网络流量分析作为一种关键技术，被广泛应用于网络安全防护、网络优化以及网络监管等领域。精细化网络流量分析是一种能更加精准地分析网络流量，并定位网络安全问题的技术，它能通过对网络流量的深入挖掘和分析，发现并防范隐藏在网络背后的威胁。因此，精细化网络流量分析具有非常重要的意义。
