Highly crystalline 2-D transition metal dichalcogenide superconductors and their associated (van der Waals) heterostructures provide a rich platform for the investigation of new quantum physics and exotic superconductivity. This is due to their 2-D non-centrosymmetric lattice with a strong spin-orbital interaction.

A National University of Singapore research team led by Prof Lu Jiong, from the Department of Chemistry, NUS in collaboration with Prof Kostya S. Novoselov from Materials Science and Engineering, NUS has developed a universal electrochemical method for the synthesis of highly-crystalline, two-dimensional superconducting monolayers (2DSC). These 2DSC monolayers are obtained in a stable suspension with monolayer production yield of up to 75%. They can be used for fabricating artificially designed structures that exhibit superconducting properties. This includes printing wafer-level 2-D superconducting wires and constructing superconducting composites using 3-D printing techniques.
