Excitons observed in action for the first time

April 16, 2014

Technique developed at MIT reveals the motion of energy-carrying quasiparticles in solid material.


Diagram of an exciton within a tetracene crystal, used in these experiments, shows the line across which data was collected. That data, plotted below as a function of both position (horizontal axis) and time (vertical axis) provides the most detailed information ever obtained on how excitons move through the material.
