摘要

本研究的重点是利用第一性原理计算钼(Mo)的电子能带结构、晶格动力学、态密度和力学性能。结果表明,Mo具有较高的导电性能。在费米能级(约0 eV)的带隙是重叠的,这是金属的特征,表明高导电性。随着温度的升高,Mo的振动能增大,而其振动自由能减小。Mo的熵和热容也随温度的升高而增大。这些发现对Mo在各种应用中的使用具有重要意义,因为它们可以帮助优化其当前用途,并可能导致新技术的开发。

Origin of Metallicity in Molybdenum: A First Principle Calculation

Origin of Metallicity in Molybdenum: A First Principle Calculation

This study focuses on the electronic band structure, lattice dynamics, density of states, and mechanical properties of molybdenum (Mo), using first-principle calculations. The results obtained show that Mo exhibits metallic behavior with high electrical conductivity. The bands gap at the Fermi level (around 0 eV) are overlapping, which is characteristic of metals and indicates high electrical conductivity. As the temperature increases, the vibrational energy of Mo rises, while its vibrational free energy decreases. Furthermore, the entropy and heat capacity of Mo also increase with temperature. These findings have important implications for the use of Mo in various applications, as they can help optimize its current uses and potentially lead to the development of new technologies.
