Superconductivity in transition metal dichalcogenides such as NbSe2 persists down to a monolayer thickness. These 2D superconductors exhibit strong spin-orbit coupling, which can render superconductivity unconventional with triplet spin pairing. This could lead to a topological superconducting state in dichalcogenide monolayers or multilayers. The aim of our project is to explore unconventional superconductivity and topological phases in heterostructures based on the stacking of transition metal dichalcogenide layers separated by magnetic or non-magnetic insulating layers. The synthesized materials will be studied by transport, tunnel spectroscopy and angle-resolved photoemission. Our experimental studies will be complemented by theoretical studies involving electronic structure calculations and analytical calculations to estimate possible superconducting phases.
