The disappeara.nce of superconductivity in ultra thin amorphous Nb films has been studied by the measurements of the electrical sheet resistance \_Rn and I-V characteristics. The mean field transition temperature Tยข0amd the Kosterlitz-Thouless transition temperature TKThaVe been determined for films
The onset of superconductivity in homogeneous ultrathin films grown incrementally is found to occur when their normal state sheet resistance falls below a value close to hl4e 2 , the quantum resistance for pairs. The data, which extends down to OAK, further suggest that in the T ~0 limit such films
