Abstract:

The temperature dependence of ultrasonic attenuation is proposed to use for determining concentration of dopand in a diluted magnetic semiconductor. This non-destructive method can be used for the crystal in which attenuation is caused by relaxation in the Jahn-Teller system. Attenuation coefficient per the impurity ion beta obtained at a fixed frequency was introduced as a parameter characterizing sensitivity of the method. This parameter was determined for a number of II-VI: 3d semiconductors: ZnSe:Ni2+, ZnTe:Ni2+, ZnSe:V2+, ZnSe:Cr2+, and ZnSe:Fe2+ at 54 MHz. Anomalously large value of beta = 23 x 10(-18) dB cm(2) was found for Cr2+ in ZnSe. (C) 2009 Elsevier B.V. All rights reserved.
