Impurity center
WitrynaImpurity centers are foreign atoms or ions that are introduced into a crystal, glass, or some other host material. To produce impurity centers in crystals, the impurity is added to the melt or solution during crystallization or is diffused into a prepared crystal. As is the case with other point defects, impurity atoms and ions may trap ... WitrynaLes impuretés suivantes sont considérées: In, Tl, Zn, Cu, Ag, Au, Ni, Pd, Pt, Co, Fe, Mn, Cr, W, O, S, Se et Te. Quelques autres impuretés qui peuvent contribuer à l'absorption infrarouge ou aux interactions entre impuretés sont également mentionnées.
