Changing the Color of Light

One of the biggest challenges in developing integrated photonic circuits — which use light rather than electrons to transport information — is to control the momentum of light. Colors of light travel at different speeds through a material but in order for light to be converted between colors, it needs to have the same momentum

UNIST Researchers Engineer Transformer-Like Carbon Nanostructure

A recent study, affiliated with UNIST has engineered a new type of carbon nanomaterials, capable of changing shapes and colors depending on the type of solvents used. Such materials have attracted much attention owing to their unique optical properties and structures. In the study, the joint research team, led by Professor Byung Soo kim and
