Volkmar Dierolf and an international team demonstrate the possibility of tuning the color of a GaN LED by changing the time sequence at which the operation current is provided to the device.
For the first time, a team of researchers from Lehigh University, Oak Ridge National Laboratory, Lebanon Valley College and Corning Inc. has demonstrated that laser-generated crystals confined in glass retain controllable ferroelectric properties, key to creating faster, more efficient optical communication systems.
