Abstract

Light-emitting diodes (LEDs) based on colloidal semiconductor nanocrystals represent a promising technology for next-generation electroluminescence displays. While ongoing efforts focus on optimizing nanocrystal properties, device performance also critically depends on the LED architecture, particularly the design of interfacial layers. Efficient charge injection and balanced carrier transport tow…
