Electrically Driven Sub‐Micrometer Light‐Emitting Diode Arrays Using Maskless and Etching‐Free Pixelation (Adv. Mater. 13/2023)

Micro‐Light‐Emitting‐Diodes Conventional methods of pixelating micro‐light‐emitting‐diodes (micro‐LEDs) via dry‐etching present many drawbacks due to induced structural damage. In article 2206945, Yong‐Hoon Cho and co‐workers report a simple pixelation methodology for micro‐light‐emitting diodes that can be scaled down to the sub‐micrometer scale using a tailored focused ion beam irradiation technique. Electrically driven sub‐micrometer‐sized pixels are successfully demonstrated without any structural deformation, enabling high‐pixel‐density displays for future applications.
