Light-Emitting Diodes: Light-Emitting Diodes with Hierarchical and Multifunctional Surface Structures for High Light Extraction and an Antifouling Effect (Small 2/2016)

Bioinspired hierarchical structures on the surface of vertical light-emitting diodes (VLEDs) are fabricated by S.-J. Park and co-workers based on combining a self-assembled dip-coating process and nanopatterning transfer method using thermal release tape. These novel surfaces reduce the total internal reflection and grant additional antifouling abilities to VLEDs. On page 161, this provides a guideline for the design of various optoelectronic devices where not only high performance but also considerably reduced contamination by the environment are required for efficient LEDs with long operational lifespans.
