Physicists score double hit in LED research

In two breakthroughs in the realm of photonics, City
College of New York graduate researchers are reporting the
successful demonstration of an LED (light-emitting diode) based on
half-light half-matter quasiparticles in atomically thin materials.
This is also the first successful test of an electrically driven
light emitter using atomically thin semiconductors embedded in a
light trapping structure (optical cavity).
