    Abstract

    We have made tunnel junctions on (SN)x and several tetracyanoquinodimethane (TCNQ) compounds by evaporation of Pb, Sn, and In and by application of a Hg-In amalgam. Junctions formed with (SN)x and HMTSeF-TCNQ show the usual gap structure of the superconducting counterelectrode when cooled to liquid-helium temperatures. Although good tunnel junctions are formed, we are not able to detect a superconducting gap in the (SN)x down to 60 mK. A broad zero-bias anomaly suggests that the surface of (SN)x consists of small particles which are not superconducting and hence are similar to (SNx) films.
