Dislocations as internal sources of infrared radiation in crystals subjected to ultrasonic influence
We have carried out a systematic study of mercury cadmium telluride crystals subjected to the high-frequency and high-intensity ultrasonic influence. The charge carrier transport parameters were determined from the Hall coefficient and conductivity measurements. Temperature dependences of the ele...

| description |
We have carried out a systematic study of mercury cadmium telluride crystals
subjected to the high-frequency and high-intensity ultrasonic influence. The charge carrier
transport parameters were determined from the Hall coefficient and conductivity
measurements. Temperature dependences of the electron concentration without and during
the ultrasonic load were calculated. A good agreement between the experimental and
theoretical data was obtained. A model of internal source of the infrared radiation
associated with a dislocation is proposed for the explanation of sonically stimulated effects in the semiconductor system. We have considered a possibility of the thermooptical excitation in Hg₁₋xCdxTe alloys during sonication, which can result in the nonequilibrium
charge carrier generation and changes in electrical parameters of the material. |
