The process of mechanical exfoliation can be simple or complex depending on the material and desired outcome. A commonly used approach is the "Scotch Tape" method, where adhesive tape is used to peel off layers from a bulk crystal. The removed layers are then transferred onto a substrate for further examination or application. The key lies in the van der Waals forces that hold the layers together; these are weak enough to allow separation without causing significant damage to the layers.
