Definition of exciton in English:

exciton

noun ɪkˈsʌɪtɒnˈɛksɪtɒnˈɛksətɑn

Physics

A mobile concentration of energy in a crystal formed by an excited electron and an associated hole.
〔物理〕激子
Example sentencesExamples
- Some of these excitons emit light when they decay to the ground state.
- The injected electrons and holes combine to form excitons, or electron-hole pairs, bound together by their mutual attraction.
- The first images of the motion of an exciton - a particle essential to modern electronics - and a biexciton show that the lighter exciton roams farther.
- As the group intensified optical stimulation during the experiments, though, the number of excitons increased and the electron/electron-hole pairs cancelled each other.
- Implicitly, the more donors, the greater the probability for a photon to become an exciton.

Origin

1930s: from excitation + -on.
