WebDoping Sn into the Cu2Te lattice can synergistically enhance the power factor and decrease thermal conductivity, leading to remarkably optimized zTs. The lone pair electrons from the 5s orbital of Sn can increase the DOS near the Fermi level of Cu2Te to promote PF and reduce κe by decreasing the carrier concentration. Web13 Nov 2024 · Electrical resistivity of Sodium is 47.7 nΩ·m. Electrical resistivity and its converse, electrical conductivity, is a fundamental property of a material that quantifies … WebWe investigated the mechanism underlying the conductivity enhancement via detailed structural analysis through Sr K-edge X-ray absorption near edge spectroscopy and X-ray diffraction and neutron powder diffraction analyses. recent advances and emerging
