Impurity trap

WitrynaIsoelectronic impurities provide scattering and trapping centers for free carriers and excitons. Intuitively, the impurity traps a carrier (electron or hole) and the latter is then trapped by Coulomb interaction with this complex. A particularly interesting case is that of iodine, which traps a hole from an electron–hole pair, thus leaving ... Witryna23 kwi 2024 · The density of traps The work carried out using chemical analyses in principle can provide density of potential traps if the analysis is quantitative. It is however not easy to anticipate the efficiency of a given moiety to act as a trap, as stated above.
