Space-Charge vs. Bulk Interstitials in AgBr Thin Films

Y. T. Tan; Harry A. Hoyen

AbstractInterstitial silver ions in silver halides may arise from two sources: Frenkel defects in the bulk and excess interstitials in the space-charge layer. The contribution of these two sources to the total interstitial concentration in thin films with different thicknesses and impurity content is examined at two temperatures.
