- Two-dimensional metal oxides play an important role in electronics and optoelectronics, and it is still a challenge to obtain thin oxides film. Here, a fluidic exfoliation method is applied to synthesis the metal oxides film by using galinstan as the reactant, and Ga2O3 film with ~1 cm size is obtained. Optical microscope and scanning electron microscope images show that the Ga2O3 film is exfoliated from the galinstan without any droplets left. Energy Dispersive X-Ray measurements confirm the existence of the Ga2O3 film. Transmission electron microscope and selected area electron diffraction patterns indicate the oxidation process do not have a prior direction. The alloy liquid based fluidic exfoliation method in room temperature provide a promising route for the synthesis of two-dimensional mental oxides, which shows significant applications in electronic and photoelectronic devices.
