Researchers transform slow emitters fast light sources
2015/11/12
Researchers from Brown University, in collaboration with colleagues from Harvard, have developed a new way to control light from phosphorescent emitters at very high speeds. The technique provides a n...
Researchers Measure How Specific Atoms Move in Dielectric Materials
Researchers Atoms Move Dielectric Materials
2015/10/13
The atomic-scale response of dielectrics/ferroelectrics to electric fields is central to their functionality. Here we introduce an in situ characterization method that reveals changes in the local ato...
