Rice scientists use light to probe acoustic tuning in gold nanodisks
Dallas TX (SPX) May 14, 2015
In a study that could open doors for new applications of photonics from molecular sensing to wireless communications, Rice University scientists have discovered a new method to tune the light-induced vibrations of nanoparticles through slight alterations to the surface to which the particles are attached. In a study published online this week in Nature Communications, researchers at Rice's Laboratory for Nanophotonics (LANP) used ultrafast laser pulses to induce the atoms in gold nanodisks to vibr ... read more
