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