Abstract

The possibility of defect structure and consequently basic parameters (carrier density, their mobility and lifetimes) control in bulk mercury-cadmium telluride (MCT) using the nanosecond laser irradiation induced shock waves (LSW) is investigated. MCT bulk samples (with composition x equals 0.2) both n- and p- type with different initial structural quality were treated. The post-treatment changes have been detected by galvanomagnetic and photoelectric (lifetime) techniques. Two depending of irradiation mode mechanisms of interaction between LSW and bulk Hg_1-XCd_XTe defect subsystem are given. The potentiality of this technique as a technological tool for controlled modification of MCT parameters is discussed.
