We present results of an experimental study concentrated on performance optimization of highly sensitive Pb -{1-x}Sn -xTe(In) terahertz photodetectors perspective for applications in the terahertz astronomy. The optimization was reached trough variation of the regime of persistent photoconductivity quenching by radio-frequency pulses. It is demonstrated that the quenching effectiveness rises rapidly with decreasing the radio-frequency in a quenching pulse. In certain regimes, the quenching boosts the photoresponse after the end of the radio-frequency pulse. Possible mechanisms of the radio-frequency quenching of the terahertz persistent photoconductivity in Pb-{1-x} Sn-xTe(In) are discussed. |
