It is estimated that there are still many thousands of atomically-thin and 2D materials still to be discovered, with applications in electronics, sensing, imagery, industrial catalysis and biomedicine.

Novel materials are fascinating for both fundamental physics and their great practical applications in electronics.
Double-dosing induces magnetism, strengthens electron quantum oscillations in topological insulator
Each of FLEET’s three research themes is significantly enabled by the science of novel, atomically-thin, two-dimensional (2D) materials.
These are materials that can be as thin as just one single layer of atoms, with resulting unusual and useful electronic properties.
To provide these materials, from bulk crystals to thin films to atomically-thin layers, FLEET draws on extensive expertise in materials synthesis in Australia and internationally.
The most well-known atomically-thin material is graphene, a 2D sheet of carbon atoms that is an extraordinarily-good electrical conductor.
FLEET scientists use other atomically-thin materials in their search for materials possessing the necessary properties for topological and exciton-superfluid states.
