DOI: 10.1002/adma.202109765
Abstract: Deep‐ultraviolet (DUV) solar‐blind communication (SBC) shows distinct advantages of non‐line‐of‐sight propagation and background noise negligibility over conventional visible‐light communication. AlGaN‐based DUV micro‐light‐emitting diodes (µ‐LEDs) are an excellent candidate for a DUV‐SBC light source due to… read more here.
