摘要
The average structure of the thermoelectric material indium antimonide (InSb) has been studied in terms of the electron density distribution using the single crystal X-ray intensity data. The charge density of this material has been studied including and excluding the quasi-forbidden h + k + l = 4n+2 type reflections using the maximum entropy method (MEM). Both the pictorial and numerical results of the experimental electron density show mixed ionic and covalent character in InSb. The use of InSb as a thermoelectric material is supported through charge density analysis.
