exciton 是什么意思

中文翻译与英英解释

n.
【物理学】激子。
adj.
-ic ,-ics n.
〔用作单数〕【物理学】激子学。
An exciton is a bound state of an electron and hole which are attracted to each other by the electrostatic Coulomb force. It is an electrically neutral quasiparticle that exists in insulators, semiconductors and in some liquids.
