A superconductor–normal metal (SN) junction is fabricated on the surface of a few-layer MoS2 flake. Superconductivity is induced by ionic liquid gating, and an h-BN flake is used to locally separate ionic liquid from the surface of MoS2. The h-BN covered channel remains semiconducting, therefore an SN junction forms at the interface between the exposed and h-BN covered MoS2 channel. Transport properties at the SN junction are studied at low temperatures and under magnetic fields. The probability of observing Andreev reflection is discussed based on the BTK model.
