Noun
exciton (plural excitons)
(physics) A bound state of an electron and an electron hole in an insulator or semiconductor
An applied electric field causes electrons and holes to move into the quantum dot layer and recombine forming an exciton that excites a QD. Source: Internet
In simpler terms, this means a local deformation of the crystal lattice around the exciton. Source: Internet
Indeed, its spatial scale is about where is effective mass of the exciton, is the exciton-phonon coupling constant, and is the characteristic frequency of optical phonons. Source: Internet
Fast optical exciton creation was used to form condensates in sub-Kelvin Cu 2 O in 2005 on. Source: Internet
The hallmark of molecular excitons in organic molecular crystals are doublets and/or triplets of exciton absorption bands strongly polarized along crystallographic axes. Source: Internet
First, self-trapped exciton states are always of a small radius, of the order of lattice constant, due to their electric neutrality. Source: Internet
