 Wedge-based mechanical exfoliation

Wedge-based mechanical exfoliation is a technique used to produce thin layers of materials, such as two-dimensional (2D) materials like graphene or transition metal dichalcogenides (TMDs), from bulk crystals. This method often involves the application of mechanical force with a wedge-shaped tool to separate layers in a controlled manner. ### Key Steps in Wedge-Based Mechanical Exfoliation: 1. **Preparation of Bulk Material**: A bulk crystal of the desired material is selected.
