Thermal Expansion and Some Characteristics of the Interatomic Bond Strength in Gallium and Indium Phosphides
Annotation
A thermometric method is used to determine the thermal expansion coefficient of an $\mathrm{InP}$ melt in the temperature range of $1331$–$1426$ K. A statistical treatment and a thermodynamic analysis of the thermal expansion coefficients for solid gallium and indium phosphides are performed using the relevant data on heat capacity. As a result, it is possible to recommend the most reliable values of the thermal expansion coefficient for these compounds in a wide temperature range. Based on these recommended data, the characteristic values of the Debye temperature and of the root-mean-square displacement of atoms from the equilibrium position are calculated, and the results are compared with the respective values obtained by other methods.
