A Korean research team succeeded in developing a metamaterial that can adjust the refractive index of light based on a molecular assembly control principle at the nanometer level by using force between molecules.  

According to the Ministry of Science, ICT and Future Planning on October 6, a research team led by professor Kim Sang-wook at the Korea Advanced Institute of Science and Technology carried out this research project and published the results in the online edition of Nature Communications on September 29.

The team is evaluated to suggest a new concept to extensively control the refractive index of a material in a wide wavelength range by securing a refractive index of five or higher in the visible light area. Through this concept, by controlling the propagation and absorption of light in optoelectronic devices such as solar cells, light-emitting diodes (LEDs) which utilize light in the visible light area, one can enhance the performances of such optoelectronic devices. 

“This research will enable us to suggest ideas about new scientific equipment such as an ultra high-magnification microscope or ultra-high-resolution semiconductor equipment,” said professor Kim about the meaning of this study.
