KAIST boosts light efficiency of eco-friendly semiconductor from 1 to 18 percent by achieving atomic-level control

KAIST said on Tuesday its materials science team led by professor Himchan Cho developed a way to improve the light-emission efficiency of an eco-friendly nano semiconductor by 18 times. The team controlled the surface of indium phosphide magic-sized nanocrystals at the atomic level, lifting efficiency from under 1 percent to 18.1 percent. The study used a precisely controlled etching strategy and was published online in the Journal of the American Chemical Society on Dec. 16.
