exciton state
physics
Quick Summary
An exciton is a mobile pairing of an electron and a positive hole within an excited crystal, often found in semiconductors. This combination, though electrically neutral as a whole, is capable of moving through the crystal and transports energy.12
When an electron within an exciton recombines with its corresponding hole, the atom is restored, and the exciton ceases to exist. This recombination can release energy as light or transfer it to a neighboring atom, potentially creating a new exciton.1
