摘要：
Photoelectric properties of lead molybdate crystals including dark current-voltage characteristics and those for illuminated crystals were investigated. The current-voltage characteristics, measured for illuminated crystals, are found to have a parabolic shape with a single local maximum. A model using the Ridley-Watkins-Hilsum theory of multivalley conduction bands is proposed to explain this shape of the current-voltage characteristics. This model is also used for the interpretation of spectral dependences of both photoconductivity and absorption of the crystals.
