Laser Processing Method Could Increase Efficiency in Optoelectronic Devices

Facebook Twitter LinkedIn Email Comments
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
