Hexagonal boron nitride (h-BN), an insulating 2D layered material, has recently attracted tremendous interest motivated by the extraordinary properties it shows across the fields of optoelectronics, quantum optics, and electronics, being exotic material platforms for various applications. At an early stage of h-BN research, it is explored as an ideal substrate and insulating layers for other 2D materials due to its atomically flat surface that is free of dangling bonds and charged impurities, an
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 for increasing pixel density results in poor external quantum efficiency (EQE), caused by the pronounced impact of defects-mediated Shockley–Read–Hall (SRH) nonradiative recombination at the etched sidewalls. Distinguishing the SRH coefficient, denoted as A coefficient, and the
Semiconductor heterostructures are essential for advancing modern technology, facilitating the development of more efficient and powerful electronic and optoelectronic devices. Conventional heterostructures, formed through the covalent bonding or the ionic bonding of distinct materials at their atomic-scale interfaces, are inherently constrained by lattice matching, which restricts material selection and design flexibility. In contrast, heterostructures involving two-dimensional layered material
Abstract The rapid advancement of next-generation photonic and electronic technologies has placed hexagonal boron nitride (hBN) at the forefront of research on two-dimensional materials. Renowned for its deep-ultraviolet band-edge emission, exceptional dielectric properties, and ability to host quantum defects, hBN offers a versatile platform for a broad range of applications. However, realizing these capabilities on a wafer scale requires an appropriate synthesis technique that not only ensures
Abstract The cordierite‐based ceramic catalyst filter (CCF) has attracted considerable attention as a promising future air purification system due to its ability to filtrate particulate matter (PM), as well as 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 of the high‐aspect‐ratio air‐flow channels, thus, only a limited portion of p
