Effect of growth-charge composition on the dark conductivity and photoconductivity of PbMoO4 crystals

The spectral response of the photocurrent through PbMoO4 crystals shows one or two bands in the range from 350 to 650 nm, depending on the growth-charge composition. These bands correlate with the corresponding bands in the transmission spectra. The dark conductivity of PbMoO4 crystals also depends...

Zusammenfassung:	The spectral response of the photocurrent through PbMoO4 crystals shows one or two bands in the range from 350 to 650 nm, depending on the growth-charge composition. These bands correlate with the corresponding bands in the transmission spectra. The dark conductivity of PbMoO4 crystals also depends on charge composition and varies from 10-7 to 10-14 S/cm. Thermopower measurements indicate that all the crystals studied arep-type.
