摘要

Abstract

BSTRACTThe present study reports the thermal conductivity and electrical transport properties of Mo

which is the first member of double-A-layer MAX phases. Dense bulk samples of Mo

C were prepared by vacuum hot pressing. At room temperature

the thermal conductivity was measured to be 14.8 ± 1.0 W/(m·K) and the electrical resistivity was 0.525 ± 0.052 µΩ·m. Mo

C follows the Wiedemann-Franz law and the Lorenz number is 2.22×10

−8

WΩK

−2

. Mo

C is a superconductor with a transition temperature of ca. 5.1 K (±0.1%). The thermal conductivity and electrical resistivity are lower than those of most MAX phases probably due to the extra Ga layer.
