Abstract:
It is established that the Schottky-barrier photovoltage decreases as a result of the irradiation of a silicon sample with a barrier by light (incident on the base side). The value of the photovoltage is restored approximately 0.5 h after irradiation. The changes in the photovoltage after irradiation are compared to the behavior of the silicon microhardness and interpreted on the basis of the concept of point defect generation in the long-range effect.
