文摘

In this manuscript we study the crystalline and superconducting properties of this system, as a possible material to be used in solid state neutron detector sensors. The results show that this superlattice system can be grown even for very thin layers, in spite of the Nb-B binary system showing many possible compounds, which could enhance interdifussion at the interfaces. Also, the superconducting properties are not degraded, and they are even enhanced with respect to those of single Nb films of the same thickness. In conclusion, we find that this system is a good potential candidate for the design and construction of solid state neutron Transition Edge Sensors.
