Researchers develop a novel way to facilitate high performance microLEDs using vertically self assembly

Researchers from Korea's Kookmin University in collaboration with colleagues from Kyung Hee University have managed to enhance the performance of microLEDs produced using fluidic self-assembly based on chelation bonds of chemical linkers. The researcher report up to 61.8% increase in assembly yield compared to previous methods, and their vertically assembled 1.3 um microLEDs achieved a peak EQE of 8.1% and a brightness of 22,300 nits at 9 V.

The researcher developed a novel approach for the face-selective vertical assembly of microLEDs using a chemical linker capable of engaging in metal chelate coordination interactions within Zn metal complexes.

The new process has three steps. First, gly-thiol (a chemical linker) is used to treat the deposited Au layer on the p-GaN surface of the microLEDs and the lower Au electrode using a self-assembly (SAM) method. In the second step, various zinc precursors are applied to the gly-thiol-treated bottom Au electrode to form metal chelate coordination bonds. Finally, the gly-thiol-treated microLEDs undergo vertical self-assembly via the chelate bond.
