Tunneling Studies of VN Thin Films
Vanadium nitride is a superconductor with the B1 crystal structure and a transition temperature of 8.8 K. The superconductivity of the refractory compounds with the B1 structure is of interest for a number of reasons. Niobium nitride is one of the earliest-known high transition temperature superconductors1 and currently is under intensive study as a possible candidate for use in electronic applications. Molybdenum nitride has been predicted2 to be a superconductor with higher Tc than NbN if its B1 crystal structure can be stabilized. Calculations3 of Tc for vanadium nitride predict a value of 32K. The fact that its Tc is much lower is explained to be the result of spin fluctuations.
