Charge transport mechanisms and photoconductivity of nanoporous granular CdS–CdSe

The photoconductivity of the CdS–CdSe granular system in the temperature range 20–120 °C was measured. It was observed that, for the studied samples, the photoconductivity steeply decreases with temperature and has a significant hysteresis. The obtained features of the photoconductivity behavior are...

Description
Summary:The photoconductivity of the CdS–CdSe granular system in the temperature range 20–120 °C was measured. It was observed that, for the studied samples, the photoconductivity steeply decreases with temperature and has a significant hysteresis. The obtained features of the photoconductivity behavior are interpreted qualitatively accounting for the nanopores existing in the studied samples.
