noun
- Plural of exciton; quasiparticles in a solid consisting of an electron and a hole bound together by electrostatic attraction.
Usage: physics; technical; used in solid-state physics and materials science
Examples
- Excitons play a crucial role in the optical properties of semiconductors.
- The researchers studied how excitons move through the crystal lattice.
- Light absorption in the material creates excitons that contribute to photocurrent.
- Excitons can dissociate into free electrons and holes under strong electric fields.
- The energy of excitons determines the color of light emitted by the LED.
