ALD passivation found to increase the efficiency of microLEDs, and improve QD color conversion technology

Researchers from the National Yang Ming Chiao Tung University (NYCU) in Taiwan have found that by applying ALD Al2O3 passivation, it is possible to increase the external quantum efficiency of microLED chips.

The EQE of 5x5 um microLEDs was enhanced by 70%, and the EQE of 10x10 um chips was enhanced by 60%. The ALD passivation technology was also successfully used for the patterning of color-conversion QDs by inkjet printing (the passivation is used to prevent the quantum dots from photo-oxidation and degradation).
