Abstract The cordierite‐based ceramic catalyst filter (CCF) has attracted considerable attention as a promising future air purification system due to its ability filtrate particulate matter (PM), well decompose volatile organic compounds (VOCs) through ultraviolet (UV)‐activated photocatalytic reactions. Its performance, however, is strictly limited because majority of UV photons are absorbed near the entrance high‐aspect‐ratio air‐flow channels, thus, only portion photocatalysts activated...
Inorganic micro-light-emitting diodes (μLEDs) have emerged as promising candidates to fulfill the demand for high-performance display technologies like immersive virtual or augmented displays. However, reducing μLED size increasing pixel density results in poor external quantum efficiency (EQE), caused by pronounced impact of defects-mediated Shockley–Read–Hall (SRH) nonradiative recombination at etched sidewalls. Distinguishing SRH coefficient, denoted A and associated energy trap levels...
