Excitons… Parmenidions… Exciting!


Getting excited can kick a person’s energy to a higher level. At the nanoscale, strange almost-particles called excitons do the same trick.

In a crystal, thin film or even some liquids, an incoming particle of light can slam into an electron, bumping it to a higher energy level and leaving a hole at the energy level where the particle had been. The exciton is the excited electron paired with the resulting hole and can move energy in two ways: by physically hopping to a new molecule or transferring energy almost like an antenna transmitting a signal. Either way, the movement is quick, with the longest-lasting exciton existing for just a few milliseconds.

Even though excitons don’t last long, scientists were recently able to make images of how the quasiparticles moved (SN Online: 4/16/14). Investigating excitons’ ability to kick around nanoscale energy could improve scientists’ understanding of photosynthesis and lead to better solar cells, LEDs and semiconductor circuits. (1)

Why not pair the whole world with all of us and discover… Parmenides?!? (what?!?)
