摘要:Liquid phase electron microscopy (TEM) is used to track the formation of In2O3 ultrathin nanosheet in solution at atomic scale. This observation reveals that the formation of few atomic layer nanosheet goes through a complicated phase transition process from InCl3.3H2O to In(OH)3 and then to In2O3. Interestingly, the intermediate InCl3.3H2O nanosheet can grow via either layer by layer or the strain-driven enation growth from precursor solution. Moreover, in situ TEM results and density functional theory (DFT) calculations demonstrate that the oleylamine is responsible for the self-peeling process. These findings can provide atomic-level insight for the understanding of how 2D nanomaterial grows and transforms in solution.
