Chemical bonding origin of the unexpected isotropic physical properties in thermoelectric Mg3Sb2 and related materials
Abstract
The outstanding thermoelectric Mg3Sb2 is currently being intensely scrutinized. Here, the authors reveal a nearly isotropic three-dimensional chemical bonding network as the origin of isotropic physical properties in Mg3Sb2, indicating the breakdown of the simple layered Zintl phase view.
