This news is about scientists at the California Institute of Technology announced in the journal Science that they have taken steps to develop a new material, just three atoms thick, that opens the door to Li-Fi, the technology that will retire the Wi-Fi we all use to transmit information over the Internet. In the study, professors of Applied Physics and Materials Science describe how they used three layers of phosphorus atoms to create a material to polarize light that is tunable, precise and extremely thin.

  • Li-Fi is a system of data transition through visible light.
  • What this technology is based on is to alter the frequency of visible light between 400-800 Hz.
  • Led bulbs are used for Li-Fi, which go at that speed,
  • this is practically unmissable for the human eye,
