Notes:
A high-temperature multicrystal x-ray diffractometer is used for measurement of elastic constants c11, c12 and the thermal-expansion coefficient of a heteroepitaxial ZnTe layer grown on a (001) oriented GaAs substrate. In addition to the standard double-crystal measurement, a new triple-crystal method is proposed. This method eliminates the angular instabilities of the high-temperature goniometer and bending of the substrate. The new method was used for determination of the thermal-expansion coefficient of a GaAs substrate. As a result of detailed discussion, the optimal experimental conditions are proposed for the limitation of the errors. © 1995 American Institute of Physics.
