Recently, liquid-metal printed processes have been developed as a novel strategy to grow ultrathin 2D oxide materials, which are transferred from liquid-metal surfaces to substrates. Previously, we have succeeded in fabricating liquid-metal printing 2D tin oxide (SnO) nanosheets on SiO2/Si substrate with a large lateral size (>0.1 mm) and atomic-level thickness (<10 nm). However, its structural characterization has not been explored. In this study, the 2D SnO nanosheets were directly fabricated on transmission electron microscope (TEM) grid via liquid–metal printing method. In the low-magnified high-resolution TEM (HRTEM) image of the 2D SnO nanosheet, the crystal grain boundaries with different orientations were observed, indicating that the nanosheet was polycrystalline SnO. The high-magnified HRTEM image showed a periodic atomic arrangement with the lattice spacing of 2.7 Å, which was assigned to the (110) crystal planes of tetragonal SnO.
