Laser Processing Method Could Increase Efficiency in Optoelectronic Devices

Facebook Twitter LinkedIn Email
WASHINGTON, D.C., April 17, 2019 — A new way to passivate defects in next-generation optical materials could improve quality in optoelectronic applications and enable the miniaturization of LEDs and other optical elements. The advance uses a laser processing technique developed by scientists at the U.S. Naval Research Laboratory (NRL). The researchers used a laser processing method to improve the optical properties of monolayer molybdenum disulphide (MoS2), a direct gap semiconductor with high spatial resolution. Monolayer MoS2 was synthesized by chemical vapor deposition (CVD) and by controlled exposure to laser light...Read full article

    GLOSSARY
    optoelectronics
    A sub-field of photonics that pertains to an electronic device that responds to optical power, emits or modifies optical radiation, or utilizes optical radiation for its internal operation. Any device that functions as an electrical-to-optical or optical-to-electrical transducer. Electro-optic often is used erroneously as a synonym.
