Abstract

Under illumination of some ferroelectrics in the intrinsic or extrinsic optical region one observes steady state photovoltaic currents as well as an accompanying photo e.m.f. which are several orders of magnitude larger than the energy gap. The temperature, lux-ampere, and spectral characteristics of the bulk photovoltaic effect in oxygen octahedral ferroelectrics and also in SbSI are investigated. Bei Belichtung einiger Ferroelektrika im optischen Grundgitter- oder Ausläuferbereich beobachtet man sowohl stationäre Photoströme als auch eine damit verbundene Photospannung, die einige Größenordnungen größer als die Bandlücke ist. Es werden die Temperatur, Beleuchtungs–Strom- sowie die Spektralcharakteristiken des Volumenphotoeffekts in oktaedrischen Sauerstoffferroelektrika sowie in SbSJ untersucht.
