Abstract Two-dimensional molecular crystals, consisting of zero-dimensional molecules, are very appealing due to their novel physical properties. However, they mostly limited organic molecules. The synthesis inorganic version two-dimensional crystals is still a challenge the difficulties in controlling crystal phase and growth plane. Here, we design passivator-assisted vapor deposition method for Sb 2 O 3 as thin monolayer. passivator can prevent heterophase nucleation suppress low-energy planes, enable molecule-by-molecule lateral along high-energy planes. Using Raman spectroscopy situ transmission electron microscopy, show that insulating α-phase flakes be transformed into semiconducting β-phase under heat electron-beam irradiation. Our findings extended controlled other open up opportunities potential electronic devices.
