Abstract

We present fabrication of a junction between an atomic layer molybdenum disulfide-based electric double layer transistor and an aluminum film, and electrical transport measurements between molybdenum disulfide (MoS2) carriers induced by strong electric fields due to its electric double-layer transistor and a conventional superconducting aluminum though Schottky barrier at the interface. A superconducting gap structure was observed in the differential resistance measurement of the dilution refrigerator temperature. Since the gap structures disappeared at about 900mK, the temperature change of this structure is caused due to aluminum superconductivity. However, as for the magnetic field change of the gap structures, the possibility of the coexistence of two kinds of superconducting states at the junction would be considered.
