Abstract :
The influence of Ag-doping on photomagnetic effect and photoconductivity in magnetic field in p-HgCdTe was investigated. Photoconductivity was measured in Faraday and Foight geometries. Such recombination parameters as lifetime, mobility of minor carriers and velocities of surface recombination are determined from this measurements using least-square fitting. Using temperature dependencies of carriers lifetime, the decrease of density of recombination centers up to two order in an investigated sample after silver doping was revealed
