  • REDUCTION IN LEAKAGE CURRENT AND INCREASE IN EFFICIENCY OF III-NITRIDE LEDS BY SIDEWALL PASSIVATION USING ATOMIC LAYER DEPOSITION
    Publication number: 20210193871
    Abstract: A reduction in leakage current and an increase in efficiency of III-nitride LEDs is obtained by sidewall passivation using atomic layer deposition of a dielectric. Atomic layer deposition is a hydrogen-free deposition method, which avoids problems associated with the effects of hydrogen on passivation and transparency.
