Query: Superconducting contacts to a monolayer semiconductor   We demonstrate superconducting vertical interconnect access (VIA) contacts to
a monolayer of molybdenum disulfide (MoS$_2$), a layered semiconductor with
highly relevant electronic and optical properties. As a contact material we use
MoRe, a superconductor with a high critical magnetic field and high critical
temperature. The electron transport is mostly dominated by a single
superconductor/normal conductor junction with a clear superconductor gap. In
addition, we find MoS$_2$ regions that are strongly coupled to the
superconductor, resulting in resonant Andreev tunneling and junction dependent
gap characteristics, suggesting a superconducting proximity effect.
Magnetoresistance measurements show that the bandstructure and the high
intrinsic carrier mobility remain intact in the bulk of the MoS$_2$. This type
of VIA contact is applicable to a large variety of layered materials and
superconducting contacts, opening up a path to monolayer semiconductors as a
platform for superconducting hybrid devices.
