Elastic Properties of Substitutional Solid Solutions InxTl1-xI and Sound Wave Velocities in Them

Abstract

Elastic properties of substitutional solid solutions In Tl1− I have been studied. The corresponding Young modulus, shear modulus, and compression modulus are calculated theoretically. The dependence of the elastic properties of the In Tl1− I solid solution on the content within the interval 0.375 ≤ ≤ 1 is analyzed. The velocity of sound propagation in examined specimens is studied experimentally. The obtained data are used to calculate the elastic coefficient 22 for In Tl1− I. The theoretical results are found to be in good agreement with experimental data.

Electronic structure and elastic properties of Cd16Se15Te solid state solution: first principles study

“…Furthermore, these properties play an important role in providing valuable information on structural stability, anisotropic factors, Debye temperature, phonon spectra and specific heat. All this information is usually defined by the elastic constants C i j [58,59]. The calculation method used allows the calculation of the total energy E for arbitrary crystal structures.…”

Оптико-энергетические свойства тонких пленок CdS, полученных методом высокочастотного магнетронного распыления

“…В настоящей работе для согласования абсолютных значений E g проведена коррекция расчетной величины на значение E = 0.73 eV. Но это не влияет на общую тенденцию электронных и структурных свойств, что подтверждено рядом предыдущих электронных расчетов [19][20][21]. поглощения прямыми межзонными оптическими переходами.…”
