Temperature Dependence of Surface Voltage of Silver Bromide

概要

論文の詳細を見る
The temperature dependence of surface voltage of silver bromide crystals has been studied. The change in the surface voltage is due to the change in the ionic space charge voltage between silver metal and silver bromide. Near and on free surface, silver ions and electrons move, and their surface levels change under the condition that their change cancels the voltage change due to the ionic space charge of this side. The curve of surface voltage vs temperature consists of two straight lines, one of which refers to the impurity region, the other refers to the intrinsic region. The more Cd the sample contains, the higher temperature the knee point moves to. The formation energy of Frenkel defect and other quantities were obtained.
