Phonon Structure

Tunneling measurements have been made on junctions consisting of aluminium separated from a second metal by aluminium oxide insulating layers. When the second metal was lead, tin, or indium, the effect of its phonon spectrum on the tunnel current was observed. Results with indium indicate that there is a broad group of phonons at an energy of 5 millivolts and another group at an energy of 13 millivolts in the indium phonon spectrum. The end point of the spectrum is at 14.8 ± 0.1 millivolts. Evidence is presented for a relationship between the strength of the phonon structure, the phonon energy, and the width of the superconducting energy gap from measurements on lead, tin, and indium. Measurements of the temperature dependence of the phonon structure in lead and indium are also reported.

Radiative Emission

A report is made of an exhaustive search for stimulated emission of energy gap radiation from superconducting tunnel junctions of the form Ta–oxide–A1. Two types of radiation detectors have been employed—bolometers for broad band detection and a superconducting frequency converter tunable in the range of interest for narrow band work. The present search has been completely unsuccessful and this negative result has spurred a reexamination of both the theory and the experiments. Serious doubts are raised as to the validity of earlier claims and it is concluded that the previous probable observation of radiative emission requires a different interpretation.
