Good Vibrations: Using Terahertz Radiation to Control Material Properties A collaboration led by researchers with the U.S. Department of Energy`s Lawrence Berkeley National Laboratory has used molecular vibrations, triggered by ultrafast pulses of terahertz radiation, to change a manganite crystal from an electrical insulator into a conductor. The ability to induce dramatic phase-changes in solid materials through select vibrations holds great promise for future exploitation of prized technological phenomena such as superconductivity and magnetoresistance.
