Single crystal growth of transition-metal carbide hexagonal-Mo2C via La-C flux method

Transition metal carbides exhibit many excellent mechanical and physical properties such as high hardness and high melting points. There are at least two phases of Mo2C: one is the hexagonal phase, another one is the orthorhombic phase. The latter one is a slightly distorted hexagonal closed-packed structure. Single crystal of the orthorhombic phase has been grown via floating zone method. In this manuscript, single crystal of hexagonal phase Mo2C, is grown via La-C flux method. Its structure and physical properties were characterized. Superconducting parameters were obtained.
