A POSTECH research team has developed a transparent amorphous silicon that transmits visible light - which permits us to distinguish the colors of objects - enabling the development of paper-thin lenses usable in head-mounted displays (HMD) that show virtual and augmented reality images in real time.

 

A research team - led by Professor Junsuk Rho of POSTECH's mechanical engineering and chemical engineering departments, and Ph.D. candidate Younghwan Yang and Dr. Gwanho Yoon of the Department of Mechanical Engineering - has developed visibly transparent amorphous silicon by improving the plasma enhanced chemical vapor deposition (PECVD) method, a practice widely used by Korean display manufacturers. The researchers also succeeded in effectively controlling the light in the visible region using the newly developed silicon. This research was recently published in Advanced Materials, the most respected international journal on materials science.

 

"The discovery of an optical element capable of controlling all visible light has revealed clues about the relationship between the atomic bonding structure and the visible light region, which has not been of interest until now," explained Professor Junsuk Rho, the corresponding author who led the study. "As we can produce optical devices that can control all colors at low cost, we are now one step closer to commercializing virtual and augmented reality and hologram technologies only seen in movies."
