UV Produces Transparent Conductor

Facebook X LinkedIn Email
A transparent electrical conductor has been produced from an insulating oxide by a team at the Tokyo Institute of Technology in Yokohama and the Japan Science and Technology Corp. in Kawasaki. The method incorporates hydrogen ions into the crystal lattice structure of the oxide by heating it in a hydrogen-rich atmosphere. Exposure to UV radiation from a xenon lamp makes the conductivity permanent. The photoactivated material exhibits approximately 0.3 S/cm-1 of conductivity at room temperature and becomes 1 percent more absorptive per 200 nm of thickness. The researchers report in the Oct....Read full article
