Investigation of photoconductivity in Pb sub 0.75 Sn sub 0.25 Te(In)

Persistent photoconductivity (PPC) at low temperature in Pb sub 0.75 Sn sub 0.25 Te(In) has been investigated using kinetic equations which describe transport processes on DX-center. We present measured and calculated photoconductivity as a function of illumination. By comparing measured and calcula...

Zusammenfassung:Persistent photoconductivity (PPC) at low temperature in Pb sub 0.75 Sn sub 0.25 Te(In) has been investigated using kinetic equations which describe transport processes on DX-center. We present measured and calculated photoconductivity as a function of illumination. By comparing measured and calculated temperature dependence of the free carrier concentration and resistivity for illuminated and unilluminated n-type samples at steady state we could estimate numeric values of mathematical model constants.
