A superconductor–normal metal (SN) junction is fabricated on the surface of a few‐layer MoS 2 flake. Superconductivity is induced by ionic liquid gating, and an h ‐BN flake is used to locally separate ionic liquid from the surface of MoS 2 . The h ‐BN covered channel remains semiconducting, therefore an SN junction forms at the interface between the exposed and h ‐BN covered MoS 2 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.
