Mechanically liberating polarization bubbles in van der Waals ferroelectrics

Spherical polar topological structures are of interest as they could enable high-density memory applications; however, such texture formation requires superlattices with delicately balanced boundary conditions to form. Here it is found that these textures can form in free-standing CuInP2S6, and that mechanical force can generate high-density domains.
