Temperature Dependence of Thermal Expansion Coefficient of (CuInTe2)1-x(2ZnTe)x Solid Solutions

Investigations have been made for the first time of the thermal expansion of the (CuInTe2)1—x(2ZnTe)x solid solutions. It has been demonstrated that the thermal expansion coefficient αL grows considerably in the temperature range from 77 to 300 K whereas the temperature dependence above 300 K is rat...

Description
Summary:Investigations have been made for the first time of the thermal expansion of the (CuInTe2)1—x(2ZnTe)x solid solutions. It has been demonstrated that the thermal expansion coefficient αL grows considerably in the temperature range from 77 to 300 K whereas the temperature dependence above 300 K is rather weak. For the solid solutions with 0 < x ≤ 0.3 a considerable change of αL(T) in the range of the solid state transition from the chalcopyrite structure into the sphalerite one takes place. Such anomaly in αL(T) has not been observed for x ≤ 0.4. The isotherms of the composition dependence of αL for 77, 293 and 500 K were constructed. They are linear within one‐phase ranges with the chalcopyrite structure (0 < x ≤ 0.3) or sphalerite structure (x ≥ 0.4). The Debye temperatures θD and the average quadratic dynamic displacements u2 were calculated.
