Abstract
The superconducting resistive transition of the layer compound Nb has been observed for crystals a few layers thick. The decreases as the crystal thickness is reduced below six Nb layers, and a of 3.8°K is predicted for a single layer. No significant increase in the transition width is observed as the number of Nb layers is reduced. The results are compared to recent work on intercalated layer compounds.
