Abstract

Despite the great number of works devoted to the research of optical, electrical and galvanomagnetic properties of double compound semiconductors CdSb and ZnSb, the information of their elastic properties, necessary to study anisotropy of chemical bond and powers of interatomic interaction in crystal lattice, is rather limited. The research of elastic properties of solid solutions Cd1-xZnxSb practically does not exist. In the given work, the supersonic wave velocity was measured by the coincidence method of reflected echo pulses on the frequency of 10 MHz. The lattice spacing was determined by the diffractometer ДРОН-ЗМ. For the first time the propagation velocities of supersonic waves υi were measured (including quasi-longitudinal and quasi-diametrical) in single crystals Cd1-xZnxSb at temperature intervals from 80 to 320K and atoms concentration Zn x=0; 0,3; 0,09; 0,125 and 1. The concentration dependencies of lattice spacing a(x), b(x) и c(x), and supersonic waves’ propagation velocities υi(T) were measured. The temperature dependencies of elastic modulus Cij(T) were calculated. For the first time the hysteresis effect at temperature dependence of propagation velocities of supersonic waves υi(T) at the temperature interval from 318 to 325K and anomalies in temperature dependencies Cij(T) were revealed. The results obtained may be used to correct the operating practices of single crystal growth, and while producing and maintaining semiconductor devices.
