A Schematic of the method of liquid interface deposition used in this study, shown in cross section for clarity. A high surface tension interface is created between DI water and distilled hexane, the ink is injected into the interface to form a film of aligned nanosheets, and the water is then evacuated by vacuum to transfer the nanosheet film onto substrates below the interface. Inset below: SEM image of a typical film, showing a high degree of flat nanosheet alignment. B Image of the setup used in the study, showing the apertures into which substrates are placed, a film is formed, and then water is evacuated via tubing placed below the water line into a vacuum chamber to transfer the films.
