First printing of Giaever's influential paper in which he demonstrated the existence of an energy gap in superconductors, one of the most important predictions of the BCS theory of superconductivity that had been developed in 1957 by Bardeen.

The present paper is regarded a contemporary classic within engineering and applied sciences.
