An exploration into two-dimensional metal oxides, and other 2D materials, synthesised via liquid metal printing and transfer techniques.

Two-dimensional (2D) metal oxides can be difficult to synthesise, and scaling up production using traditional methods is challenging. However, a new liquid metal-based technique, that utilises both “top-down” and “bottom-up” processes, has recently been introduced. These liquids oxidise to form an oxide surface “skin” which may be exfoliated as a 2D flake and subsequently used in various electronic devices and chemical reactions.
