Photoconductive and photorefractive effects in BSO.
The photoconductivity of BSO was investigated through the dependence of the photocurrent on wavelength and power. The variation of the photocurrent and the photorefractive effect as a function of the mode of illumination was determined. The evidence indicates that different transport mechanisms (with different transport parameters) are effective in the photoconductive and photorefractive effects. Hopping mechanisms appear to be important in charge transport in these materials.
