摘要：

The results of the investigations of the transport properties of n- and p-CdxHg1-xTe semiconductor crystals behavior at intensive ultrasonic (approximate to 6MHz) are presented. Acoustostimulated phenomenon of mobility increasing and change of concentration ( increasing in n-type and decreasing in p-type) are observed in region of impurity conductivity. The possible mechanisms of the acoustodynamic processes (electrical activation/disactivation of the crystals defects, reducing of alloy scattering) are analyzed. At first the phenomenon of the acoustostimulated p-->n conversion had been detected in p-CdxHg1-xTe at T<120 K.
