Nature Synthesis - A mechanical exfoliation method for producing freestanding metal oxide ultrathin flakes is reported. The flakes can be transferred and integrated with 2D materials, providing...

Mechanical exfoliation of layered materials is one of the most effective methods for obtaining two-dimensional (2D) nanosheets. However, this approach is still limited to van der Waals (vdW) layered materials, where interlayer interactions are governed by weak vdW forces. In this study, we used a layered perovskite ferroelectric ...

Here we introduce a contamination-free, one-step and universal Au-assisted mechanical exfoliation method and demonstrate its effectiveness by isolating 40 types of single-crystalline monolayers...

Using mechanical exfoliation, we isolate single-crystalline flakes of the perovskite and transfer these to microscopy slides.

The mechanical exfoliation method was used to exfoliate the PEPI perovskite single crystal. This involved using 3 M Scotch tape for repeated exfoliation until the surface layers with high density of impurities were removed.
