Figure: Cross-section TEM image of a Mo/Au bilayer deposited on a Si3N4 membrane; room temperature growth is required to prevent strains in the Mo layer and Si3N4 membrane. Columnar morphology is appreciated, as well as a flat, sharp Mo/Au interface, which results in very narrow superconducting transitions.
