Paper Abstract

Ultrasonically stimulated effects in Hg1-xCdxTe alloys were studied. Dependencies of Hall coefficient and conductivity of n- and p-MCT samples from temperature ( T=77÷300° K ) and magnetic field ( B=0÷0.7 T ) were investigated during ultrasonic influence and after ultrasonic treatment with frequency fUS = 5÷8 MHz and intensity WUS ⪝ 0.5•104 W/m2. It was shown that the action of the acoustic wave excited in Hg1-xCdxTe crystal by piezo-transducer results in an essential change of the carrier concentration up to change of the conduction type. The possible mechanism of sonic-stimulated effects was discussed in the frame of the intensive sonic-dislocation interaction model. The possibility of the thermooptical excitation of solid with activation of internal sources of the infrared radiation as a consequence of the acoustic wave energy absorption was determined.
