Debye–Waller factors and Debye temperature of ZnTe

Accurate measurements were made to determine the Debye temperature and Debye-Waller factors for powder ZnTe by the method of elastic neutron diffraction, using a triple-axis neutron spectrometer. Measurements were made with neutrons of wavelength 1.17 Å and corrections were made for the thermal diffuse scattering. The values of the Debye-Waller factors are B_Zn = 1.26 (5) and B_Te = 0.74 (5) Ų. The mass-weighted mean value is 0.91 (5) Ų which corresponds to a Debye temperature Θ = 198 (5)K. The results are in good agreement with the values determined by Cooper, Rouse & Fuess [Acta Cryst. (1973), A29, 44-56] using single-crystal neutron diffraction techniques.
