The severely insufficient operational lifetime of perovskite light‐emitting diodes (LEDs) is incompatible with the rapidly increasing external quantum efficiency, even as it approaches the theoretical limit, thereby significantly impeding the commercialization of perovskite LEDs. In addition, Joule heating induces ion migration and surface defects, degrades the photoluminescence quantum yield and...
Perovskite Nanocrystal Light‐Emitting Diodes
In article number 2303472, Do‐Hoon Hwang, Bo Ram Lee, and co‐workers design crosslinked poly(FCA60‐co‐BFCA20‐co‐VFCA20) as a temperature‐dependent hole transport layer for perovskite nanocrystal light‐emittingdiodes (LEDs), balancing charge injection, reducing interface exciton quenching and Joule heating. The effective thermal management of the working...
This study suggests a Ru/ZnO bilayer grown using area‐selective atomic layer deposition (AS‐ALD) as a multifunctional layer for advanced Cu metallization. As a diffusion barrier and glue layer, ZnO is selectively grown on SiO2, excluding Cu, where Ru, as a liner and seed layer, is grown on both surfaces. Dodecanethiol (DDT) is used as an inhibitor for the AS‐ALD of ZnO using diethylzinc and H2O at...
Here, a simplified synthesis of graphitic carbon nitride quantum dots (g‐C3N4‐QDs) with improved solution and electroluminescent properties using a one‐pot methylamine intercalation–stripping method (OMIM) to hydrothermally exfoliate QDs from bulk graphitic carbon nitride (g‐C3N4) is presented. The quantum dots synthesized by this method retain the blue photoluminescence with extremely high fluorescent...
