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 ...
