Sažetak

Single crystals of KCl, KBr and KCl : KBr have been grown by Kyropoulos method. Electron injection has been employed in these crystals through heterogeneous contacts under different temperature and applied electric fields. The ionic zone followed by electron traping zone is observed and simultaneous current growth and optical absorption have been studied during traping zone. Before the advent of third zone the original transparence of the crystal is regained with the decay of induced defect centers. From the decay time, mobility of these centers and thereby activation energy involved for their migration have been obtained.
